## Practise Questions with Solutions from the How to Crack Test of Reasoning in All Competitive Exam

- (a)Puppy
- (b)Kid
- (c)Lamb
- (d)Colt

**Hint**

The second element is the young one of the first element.

**Solution:**

After observing the question, we get that

As 'Calf' refers particularly to the young one of 'Cow'.

Similarly, 'Kid' refers particularly to the young one of 'Goat'.

However, puppy, lamb, and colt are the young ones of dog, sheep, and horse respectively.

Hence, Kid is the correct answer.

- (a)Tennis
- (b)Badminton
- (c)Gymnastic
- (d)Wrestling

**Hint**

The second element (game/sport) is played on the first element (place/area).

**Solution:**

After observing the question, we get that,

'Cricket' is played on 'Pitch'. Pitch is a place containing a central strip in the cricket field between the two wickets, where the batsman and the bowler faces each other.

Similarly, 'Wrestling' is done in 'Arena'. An arena is a place surrounding by seats where public entertainments (sports, concerts, etc.) are held.

Hence, option (D) is correct.

- (a)Milk : Food
- (b)Bud : Flower
- (c)Soil : Erosion
- (d)Mosquito : Malaria

**Hint**

The second word is the disease caused by the first word.

**Solution:**

After observing the question, we get that

Tobacco is a substance smoked in cigarettes whose use leads to cancer (a deadly disease).

So, 'Tobacco' is a cause of 'Cancer'.

Similarly, malaria is an ailment caused by the bite of an infected mosquito.

So, 'Mosquito' is the cause of 'Malaria'.

Hence, option D is correct.

- (a)Devastation
- (b)Havoc
- (c)River
- (d)Drought

**Hint**

Havoc means widespread destruction.

**Solution:**

After observing the question, we get that the Cyclones are regions of relatively low pressures and their circulation is counterclockwise, whereas anticyclones are regions of high pressures and their circulation is clockwise.

So, 'Cyclone' is the opposite of 'Anti-cyclone.” Similarly, a flood refers to an overflow of water beyond its limits, while drought is a situation of prolonged shortages in the water supply.

So, 'Flood' is the opposite of 'Drought.”

However, devastation and havoc refer to great destruction or damage.

Hence, option D is correct.

- (a)Customer
- (b)Criminal
- (c)Magistrate
- (d)Client

**Hint**

The first element deals with the second element.

**Solution:**

After observing the question, we get that,

As 'Doctor' deals with a 'patient'.

Similarly, a 'Lawyer' deals with a 'client' (a person who wants professional support or service).

However, a customer is a person who buys products or services from the company or an organisation, while a magistrate deals with criminals.

Hence, option D is correct.

Check the use of words (for single or multiple persons).

**Solution:**

Let us carefully examine each option and find a connection between them, whichever is not connected will be an odd one.

The related words can be opposite or identical in meaning, nature or can vary in their degree of representation.

To find the odd one out we need to find the property or pattern which common to three options.

After observing each option we find that, agitation, commotion and annihilation are done in group.

But confusion can be felt by an individual.

Hence, option B is the correct answer.

- (a)Poland
- (b)Korea
- (c)Spain
- (d)Greece

**Hint**

Only one country belongs to asian continent.

**Solution:**

Let us carefully examine each option and find a connection between them, whichever is not connected will be an odd one. The related words can be opposite or identical in meaning, nature, or can vary in their degree of representation.

To find the odd one out we need to find the property or pattern which common to three options.

After observing each option we find that,

Poland, Spain, and Greece are European countries that mean they are situated in Europe.Korea is an Asian country that means they are situated

Hence, option B is the correct answer.

- (a)Bang
- (b)Hiss
- (c)Whistle
- (d)Wink

**Hint**

Words are related to sound.

**Solution:**

Let us carefully examine each option and find a connection between them, whichever is not connected will be an odd one.

The related words can be opposite or identical in meaning, nature or can vary in their degree of representation.

To find the odd one out we need to find the property or pattern which common to three options.

After observing each option we find that, except wink, all others are different types of sound.

Hence, option D is the correct answer.

- (a)MNW
- (b)OPY
- (c)JKT
- (d)GHO

**Hint**

The difference between first and second and second and third letter in every group is constant except for one.

**Solution:**

To find the odd one out we need to find the property or pattern which common to three options.

Here the pattern is, difference between first and second letter is $1$ and that between second and third letter is $9$.

$M\stackrel{+1}{\to}N\stackrel{+9}{\to}W$

$O\stackrel{+1}{\to}P\stackrel{+9}{\to}Y$

$J\stackrel{+1}{\to}K\stackrel{+9}{\to}T$

But,

$G\stackrel{+1}{\to}H\stackrel{+7}{\to}O$

So, it is clear from above that $GHO$ is different from others.

Hence, option D is the correct answer.

**Hint**

Count the places of letters in the alphabetical series and find the letters at 6th and 14th place.

**Solution:**

In letter series the letter follow a definite order. The given series of letters can be in natural order or in reverse order or combination of both. Let us carefully examine each option and find a connection between them, whichever is not connected will be an odd one.

There are twenty - six letters in the alphabetical series. So, the alphabetical series-

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

As per question

Letter from left at position = F

Next $14th$ position right from ‘F’ = $6+14=20th$ position from left

i.e. T

So option (d) is correct.

- (a)N
- (b)M
- (c)P
- (d)O

**Hint**

There are twenty - six letters in the alphabetical series. So, the alphabetical series-

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

As per question

$7th$ letter from right = $20th$ letter from left

Midway of $8th$ and $20th$from left = $(8+20)/2=14th$ letter from left

i.e. N

Hence option (a) is correct.

- (a)G
- (b)H
- (c)S
- (d)R

**Hint**

Count the places of letters in the reverse alphabetical series and find 18th letter from right.

**Solution:**

In letter series the letter follow a definite order. The given series of letters can be in natural order or in reverse order or combination of both.

There are twenty - six letters in the alphabetical series. So, the alphabetical series in reverse order-

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A

When English alphabet written in reverse order.

Position of ‘M’ from right = $13$

$5th$ to the Left of M = $13+5=18th$ letter from right

i.e. R

Hence option (d) is correct.

- (a)A
- (b)B
- (c)C
- (d)D

**Hint**

Count the places of letters in the reverse alphabetical series and find 4th letter from right.

**Solution:**

There are twenty - six letters in the alphabetical series. So, the alphabetical series in reverse order-

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A

When we write alphabet in reverse order

Position of K from right = $11$

$7th$ to right of K = $11-7=4th$letter from right = D

Hence option (d) is correct.

- (a)W
- (b)H
- (c)R
- (d)D

**Hint**

Count the places of letters in the reverse alphabetical series.

**Solution:**

In letter series the letter follow a definite order. The given series of letters can be in natural order or in reverse order or combination of both. There are 26 letters in the alphabetical series. So, the alphabetical series in reverse order-

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A

When alphabet write in reverse order

11th position from right = K

7th to left of K = 18th (11+7) letter from right = RHence, option (c) is correct.

**Hint**

Observe the pattern in the omission of letters from each term to obtain next term.

**Solution:**

In this series the pattern followed is :

The last letter is omitted from the first term to get next term and then the first letter is omitted to get next term and so on.

NATURAL $\Rightarrow $ NATURA is the next term as L is omitted.

NATURA $\Rightarrow $ ATURA is the next term as N is omitted.

Now, ATURA $\Rightarrow $ ATUR as the last letter is removed.

Hence, ATUR is the next term of the series.

Therefore, the correct answer is option A.

- (a) LMNO
- (b) NOPQ
- (c) KLMN
- (d) MNOP

**Hint**

The number of letters being skipped between the two consecutive terms is increasing at a constant rate.

**Solution:**

In this series, the number of letters in each term goes on increasing from $1,2,3,4,5$ and so on.

Also, the gap between the terms goes on increasing.

Between the first and the second term, the gap is of one letter.

Between the second and the third term, the gap is of two letters.

So between the third and the fourth term gap will be of three letters and the number of letters will be $4$.

Hence, MNOP is the required term of the series.

- (a) XXXXXXX
- (b) YXXXXXX
- (c) YYYYYYX
- (d) YYXXXXX

**Hint**

One letter is being replaced by the other in a definite pattern.

**Solution:**

In this series, the second letter X is replaced by Y in the first term to get next term.

YXXXXXX $\Rightarrow $ YYXXXXX

The third letter X is replaced by Y in the second term to get next term.

YYXXXXX $\Rightarrow $ YYYXXXX

The fourth letter X is replaced by Y in the third term to get next term.

YYYXXXX $\Rightarrow $ YYYYXXX

The fifth letter X is replaced by Y in the fourth term to get next term.

YYYYXXX $\Rightarrow $ YYYYYXX

The sixth letter X is replaced by Y in the fifth term to get next term.

YYYYYXX $\Rightarrow $ YYYYYYX is the next term of the series.Hence, the correct option is C.

- (a)A
- (b)V
- (c)U
- (d)W
- (e) None of these

**Hint**

There are two series combined, one begins with ABCD and the other begins with PQRS.

**Solution:**

It is a combination of two series.

The first series is ABCD, ABCDE, ABCDEF.

In this series after last letter i.e. D next letter is added to get next term which is E and so on.

The second series is PQRS,PQRST.

According to the pattern, next term will be PQRSTU.

Hence, the correct option is C.

- (a)U
- (b)A
- (c)B
- (d)Z
- (e) None of these

**Hint**

Here the combination of two series is analysed and some letters are omitted to obtain the next term.

**Solution:**

It is a combination of two series.

The first series is ABCDEF, ABCDE, ABCD.

In this series, the last letter in the first term is omitted i.e. F to get next term.

The second series is ZYXWVU, ZYXWVU, ZYXWVU.

Hence, according to this pattern, U is the next letter of the series.

The pattern is:

The middle number$=$(Number I$-$Number II)^{$2$}

According to the first figure,

$9=(7-4{)}^{2}\phantom{\rule{0ex}{0ex}}9={3}^{2}$

In the second figure,$4=(9-7{)}^{2}\phantom{\rule{0ex}{0ex}}4={2}^{2}$

Similarly, in the third figure-$x=(11-7{)}^{2}\phantom{\rule{0ex}{0ex}}x={4}^{2}\phantom{\rule{0ex}{0ex}}x=16$

In simple terms,

The middle number is the square of the difference of corner numbers.

Similarly, in the second diagram,$8\times x=48\phantom{\rule{0ex}{0ex}}x=48\xf78\phantom{\rule{0ex}{0ex}}x=6$

And, $16+6=22$

In simple terms,

Two numbers are multiplied diagonally to get the last number and another one is added.

Hence,, option (B) is correct.

- (a)F and $75$
- (b)E and $65$
- (c)D and $60$
- (d)C and $58$

**Hint**

Apply addition or subtraction of given numbers.

**Solution:**

Let the missing number be x and the missing alphabet be y.

In the first diagram,According to the pattern of the alphabet,

A$-$B$-$C$-$D, D$-$E$-$F$-$G, G$-$H$-$I$-$J

According to the pattern of numbers,$(7+9)\times 2+\sqrt{4+5}\phantom{\rule{0ex}{0ex}}=16\times 2+3=32+3=35$

Similarly, in the third diagram-

According to the pattern of the alphabet,

Y$-$Z$-$A$-$B, B$-$C$-$D$-$E, E$-$F$-$G$-$H

So, y$=$E

$(10+21)\times 2+\sqrt{3+6}\phantom{\rule{0ex}{0ex}}=31\times 2+3=62+3=65$In simple terms,

Every alphabet is as a gap of two alphabets and for the numbers, top two numbers are added and multiply by $2$ and the sum of the square root of both numbers which are in the bottom are added to get the middle number.

Hence, option (B) is correct.

- (a)$9$
- (b)$3$
- (c)$6$
- (d)$2$

**Hint**

Apply multiplication or subtraction of given numbers.

**Solution:**

Let the missing number be x.

The pattern is: Middle number$=$(Top number$\times $Bottom number)$-$(left number$\times $positional value of alphabet)

In the first diagram,The positional value of S is $19$.

$15=(8\times 9)-(3\times 19)\phantom{\rule{0ex}{0ex}}15=72-57$Similarly, in the third diagram-

The positional value of K is 11.$8=(5\times 6)-(x\times 11)\phantom{\rule{0ex}{0ex}}8=30-(x\times 11)\phantom{\rule{0ex}{0ex}}x\times 11=30-8\phantom{\rule{0ex}{0ex}}x\times 11=22\phantom{\rule{0ex}{0ex}}x=22\xf711\phantom{\rule{0ex}{0ex}}x=2$

In simple terms,

Top number multiply by bottom number and subtracted from the multiplication of the left number and positional value of the right alphabet to get the middle number.

Hence, option (D) is correct.

Try to find out first, in $12$ hours, how many times the clock hands are in opposite directions then double it for a day.

**Solution:**

In every $12$ hours the hands of a clock points in opposite directions, $11$ times (as between $5$ and $7$ they point in opposite directions at $6$ o'clock only).

So, in a day of $24$ hour, the hands point in the opposite directions $22$ times.

Hence, we can conclude that the correct choice of option is B.

- (a)$11$
- (b)$6$
- (c)$90$
- (d)$10$

**Hint**

Use the concept that in $12$ hour hands of a clock are at the right angle for $22$ times.

**Solution:**

We know that,

In $12$ hours the hands of a clock at right angle $22$ times.

As per the given question from $4$ pm to $10$ pm, there are $6$ hours i.e., the hands will be at right angles $11$ times.We can see two right angles are formed during each hourly period $4-5,5-6,6-7,7-8,8-9.$

However, when the clock reaches $9$ pm, this coincides with the second $90$ degree between the hours of $8-9$. The clock has then to reach approximately $9:34$ pm for the only occasion when the hands are $90$ degree in the hours $9-10$.

Hence, option A is correct.

- (a)${180}^{o}$
- (b)${150}^{o}$
- (c)${210}^{o}$
- (d)${200}^{o}$

**Hint**

Use the concept that in 6 hour angles covered is equal to ${180}^{}$

**Solution:**

We know that angle covered by hour hand in $12\mathrm{hours}=360\xb0$

For $8$ to $2$, there are $6$ $\mathrm{hours}$.

Angle covered by the hour hand in$6\mathrm{hours}=6\times (360\xf712)$ $=180\xb0$

Hence, we can conclude that the correct choice of answer is option A.

- (a)${90}^{o}$
- (b)${75}^{o}$
- (c)${60}^{o}$
- (d)${85}^{o}$

**Hint**

Use the concept that in one round hands of clock covers ${360}^{\xb0}$.

**Solution:**

As per the given question, we have to find the angle between the hour and minute hand.

Using the concept that in clock a full round equal to $360\xb0$

Angle covered by hour hand in hours$=(30\times 8)\xb0=240\xb0$

Angle covered by the minute hand in minutes$=\left(\right(11\xf72)\times 30)\xb0=165\xb0$

Therefore, the required angle $=240-165=75\xb0$Hence, we can conclude that the correct choice of answer is option B.

- (a)${10}^{o}$
- (b)${12}^{o}$
- (c)${15}^{o}$
- (d)${18}^{o}$

**Hint**

Calculate the angle sweeped in one sector and proceed further.

**Solution:**

Using the concept that an analog clock is divided up into $12$ Sectors. Based on the numbers $1-12$.

One sector represents ${30}^{\xb0}$ $=\frac{{360}^{\xb0}}{12}\phantom{\rule{0ex}{0ex}}={30}^{\xb0}$

Angle covered by hour hand in hours $=(30\times 5)\xb0=150\xb0$

Angle covered by minute hand in minutes $=((11\xf72)\times 30)\xb0=165\xb0$

Therefore, the required angle $=165-150=15\xb0$Hence, we can conclude that the correct choice of answer is option C.

C is an engineering specialist, E is a computer specialist and both are working in Y company.

**Solution:**

According to the information given in the question, D, working in a company X has specialised in HR and her friend G, a finance specialist is working in company Z.

From this information, we can say D is a female and has specialised in HR. G may be male or female.

H, an HR specialist, is working with B, a marketing specialist and does not work in company Y. C is not a computer specialist.

No two people with the same specialisation, work together.

It means H is a male and B may be male or female working in the same company.

B does not work in Y. D and H have the same specialisation. Therefore, H does not work in X. H and B work in Z company.

F is a specialist in marketing working in company Y and his friend, A is a specialist in finance and is working in company X with only one other specialist. So F is male and A is also male because company X has a female, and no two females are in the same company.

Not more than three of them work in any company. No female is an engineer or computer specialist.

C is not a computer specialist. Then C is engineer and E is a computer specialist and both are male. They do not work in Z because in Z company there are already three persons. Therefore, C and E work in Y company.

From the above information, we can draw the table as shown below

Person Company Gender Specialisation D X Female HR G Z Male/Female Finance H Z Male HR B Z Male/Female Marketing F Y Male Marketing A X Male Finance C Y Male Engineer E Y Male Computer We can see clearly from the table that X and Z companies do the HR specialist work.

The present age of Vinay is 4 years.

**Solution:**

According to the question,

Age of Sami$=12yr$

Sami is three times as old as his brother Vinay.

So, Vinay's age $=\frac{12}{3}=4yr$

As per the question,

Let, after $ayears$ Sami will be twice as old as Vinay.

$12+a=2\left(4+a\right)\phantom{\rule{0ex}{0ex}}12+a=8+2a\phantom{\rule{0ex}{0ex}}12-8=2a-a\phantom{\rule{0ex}{0ex}}a=4yr$

So, $4years$ from now Sami will be twice his brother's age.

Hence, age of Sami$=12+4=16yr$.

Argument II is weak because online shopping portals allow the customers to compare a large variety of products in various categories which is not possible practically in the retail stores as every model is not available all the time.

Argument III is weak because online shopping portals over the cash on delivery feature along with the online payment which is encouraging more for the customers who don't believe in online payments to shop more on online shopping portals.

Argument IV is weak because it is not true that consumers prefer retail stores just because they are nearby, they choose according to the availability of the products they need.

Argument V is strong because it is one of the biggest drawbacks in online shopping as the customer can't touch the product and unable to see how it works. In this case, in customer may get deceived as he doesn't know how it looks in reality.

- (e)If the data in both statements together are necessary to answer the question

**Hint**

In statement I, K is taller than all others, but is not the tallest.

**Solution:**

From Statement 1, the buildings according to increasing heights are:

$O/JMNKL$

Hence, $L$ is the tallest.But in Statement 2,

$O<J<N<K<M/L$

Here we can not say that which building is tallest.

Hence, Statement 1 is alone sufficient but Statement 2 is not sufficient.

- (a) If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question
- (b) If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
- (c) If the data either in statement I alone or in statement II alone is sufficient to answer the question
- (d)If the data even in both statements together are not sufficient to answer the question
- (e)If the data in both statements together are necessary to answer the question

**Hint**

First, find the direction of Q with respect to M and K.

**Solution:**

As per statement I,

The direction of P is away from Q is given specific direction is not defined and so direction of M is not defined. So, we cannot find direction of M with respect to K.

From Statement II,

K is to South East of Q which is South of M. So, K is also South East of M.

Hence, statement II is sufficient.

- (a)If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question
- (b)If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
- (c)If the data either in statement I alone or in statement II alone is sufficient to answer the question
- (d)If the data even in both statements together are not sufficient to answer the question
- (e)If the data in both statements together are necessary to answer the question

**Hint**

In statement I, find the relation of M and P with respect to R.

**Solution:**

From Statement I,

M and I are children of R, G is only daughter of M and C. But, R has a granddaughter, so P is daughter of I. Hence, M is her Maternal Aunt.

From Statement II,

M is only child of R and G is child of M. But, P is grand child of R, and it's relation with M is not defined. Hence, we cannot say how P is related to M.

Hence, statement II is not sufficient.

- (a) If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question
- (b)If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
- (c)If the data either in statement I alone or in statement II alone is sufficient to answer the question
- (d)If the data even in both statements together are not sufficient to answer the question
- (e)If the data in both statements together are necessary to answer the question

**Hint**

Mark the position of M and Q according to the statements given.

**Solution:**

From statement I, the floor arrangement are:

N, Q, M, _, P and O will come in the second floor.

In Statement II, we get the arrangement as:

P will occur in the lowermost floor.

So, from topmost to lowermost the arrangement is N, Q, M, O, P. There are no people living between M and Q.

So we can say that both Statement I and Statement II alone are sufficient to answer the question.

- (a)
If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question

- (d)If the data even in both statements together are not sufficient to answer the question
- (e)If the data in both statements together are necessary to answer the question

**Hint**

Both the statements cannot find who is sitting at the extreme left individually.

**Solution:**

From Statement I, the arrangement can be:

V P Q

V Q P From Statement II, the arrangement can be:

W V Q R

V W R Q Even if we combine both statements, only place of W and P is fix and other member places are not fixed. So, we can say that from both the statements it is not clear who is sitting in the end of the rows.

Hence, the correct answer is if the data even in both statements together are not sufficient to answer the question
