State Bank Probationary Officers Preliminary Examination

The word ‘than’ is used to compare things. When ‘than’ is used in a sentence, it should be used after a comparative adjective. But, ‘different’ is not a comparative adjective. ‘Than’ can be used after ‘different’ only when ‘different’ is followed by a noun. Here, ‘than’ should be replaced with ‘from’.

The correct form of the sentence is, “Nobody can deny the fact that Indian economy is very different from American economy”.

‘With regard’ is the accurate phrase that has been followed throughout the history. Whenever the preposition ‘with regard’ is used, it indicates the reference to a particular subject/topic. ‘With regards’ is considered as a grammatically incorrect phrase.

The correct form of the sentence is, “Accurate statistics with regard to the area occupied in different forms of cultivation are different to obtain."

The use of ‘seldom if ever’ gives possibility for an event to happen, whereas using ‘seldom or never’ provides no possibility for that event to happen.  Therefore, ‘seldom or never’ is the correct usage in the given sentence.

The correct form of the given sentence is, "Seldom or never was there any training or instructions in such tactics for either the tank crews or the infantry formations."

The preposition ‘than’ is used for comparing one thing with another, which is not needed in the given statement. The action of smelling has already been done, therefore the past participle of smell (smelled) should be used.

The correct form of the sentence is, “As soon as I opened the front door of my house, I smelled the distinctive aroma of fresh coffee."

There is no need of usage of any conjunction in the given sentence. 'Although' and 'though' is followed by ‘yet’ and not by ‘but’. 'But', 'else', 'or', etc., are not required.

The correct form of the given sentence is, “Although he had fewer supporters among the governing class, he was able to get the popular vote”.

Given:

Thirty-five percent of $740$ is $34$ more than a number.

Let $x$ be the given number.

Thirty-five percent of$740$is $34$ more than a number can be written as

$$\begin{gathered} 35\%\times 740=34+x \\ \frac{35}{100}\times 740=34+x \\ 3.5\times 74=34+x \\ 259=34+x \\ x=259-34 \\ x=225 \end{gathered}$$

Now, the number is $225$.

Therefore, the two-fifth of the obtained number is 

$$\begin{gathered} \frac{2}{5}\times 225=2\times 45 \\ =90 \end{gathered}$$

Thus, the two-fifth value of the obtained number is $90$.

Given:

A train is covering $1235 km$ in $19 hours$.

By using the formula, $Speed=\frac{\text{Distance travelled}}{\text{Time Taken}}$

Then, the speed of the train $=\frac{1235}{19}=65 \mathrm{km}/\mathrm{hr}$

Average speed of a car $=\frac{4}{5}\times 65=52 \mathrm{km}/\mathrm{hr}$

By using the formula, $Distance=Speed\times Time$

Then, the car will cover the distance in $22 hours$ will be

$=52 km/hr\times 22 hr=1144 km$

Thus, the required distance $= 1144 km$

Given that, the selling price is $₹ 6,750$ incurred a loss of $25\%$
$\mathrm{Cost} \mathrm{Price} = \frac{\mathrm{Selling} \mathrm{Price}\times 100}{100-\mathrm{Loss}\%}$

On plugging in the given values we get,

$$\begin{gathered} \text{Cost price }=\frac{6750\times 100}{100-25} \\ \mathrm{CP}=\frac{675000}{75} \\ \mathrm{CP}=₹9000 \end{gathered}$$

$\text{Selling price}=\frac{\text{CP}\times (100+\text{Profit \%})}{100}$

We get,

$$\begin{gathered} \text{Selling price }=\frac{9000\times (100+15)}{100} \\ \mathrm{SP}=\frac{9000\times \left(115\right)}{100} \\ \mathrm{SP}=90\times 115 \\ \mathrm{SP}=10350 \end{gathered}$$

Therefore, the required selling price of the item is $₹10,350$

Given,

$(0.7{)}^2÷(0.343)=(0.7{)}^{?}÷(0.49{)}^3$

We can write the above equation like this,

$\frac{(0.7{)}^2}{(0.7{)}^3}=\frac{(0.7{)}^{?}}{{\left[\right(0.7{)}^2]}^3}$

$\frac{(0.7{)}^2}{(0.7{)}^3}=\frac{(0.7{)}^{?}}{(0.7{)}^6}$

According to the mathematical protocol, the above step is written like this,

$(0.7{)}^{2-3}=(0.7{)}^{?-6}$

Now to find the question mark,

$?-6=2-3$

We can take RHS number to LHS, so that the negative sign can be changed as positive,

$?=6-1=5$

Thus, the answer is option E.

We know that, $\mathrm{Area} \mathrm{of} \mathrm{rectangle} = \mathrm{Length}\times \mathrm{Breadth}$

Given that, the area of the rectangle is $112 sq cm$ and breadth is $8 cm$. On substituting the values in the above formula we get,
$$\begin{gathered} 112=\text{length}\times 8 \\ \text{length}=\frac{112}{8}=14 cm \end{gathered}$$

Therefore, the length is $14 cm$.

Perimeter of the rectangle, $\mathrm{p}=2\times (\mathrm{l}+\mathrm{b})$

On substituting the values we get,

$\mathrm{p}=2\times (14+8)=2\times 22=44$

Therefore, the perimeter is $44 cm$.

Given that, the sum of the circumference of the circle and the perimeter of the rectangle is $132 cm$.

Let us consider the circumference of the circle as $x$ and we know that the perimeter is $44 cm$

$$\begin{gathered} \therefore x+44=132 \\ x=132-44=88 \end{gathered}$$

The circumference is $88 cm$ that is, 

$$\begin{gathered} 2\mathrm{\pi r}=88 \mathrm{cm} \\ 2\times \frac{22}{7}\times \mathrm{r}=88 \\ \mathrm{r}=\frac{88\times 7}{2\times 22}=14 \end{gathered}$$

Therefore, the radius is $14 cm$.

Hence, the area of the circle is,
$\mathrm{Area}={\mathrm{\pi r}}^2=\frac{22}{7}\times 14\times 14$

On calculating we get,

$$\begin{gathered} \mathrm{Area}=22\times 2\times 14=44\times 14 \\ \mathrm{Area}=616 {\mathrm{cm}}^2 \end{gathered}$$

The required area of the circle is $616 sq cm$.

The error lies in the fourth part of the sentence. We have to change "who" to "which" to make the sentence meaningful. To refer to inanimate objects or abstract things, we use the relative pronoun 'which'. To refer to human beings, we use the relative pronoun 'who'.  Here in the given sentence, we are talking about the chain events, so the proper relative pronoun is 'which'.

The statement describes a general statement of facts. In such cases, we need to use the simple present/ present indefinite tense. The present indefinite tense is maintained throughout the sentence. The verb 'is' is also correctly used.
So, the sentence is grammatically correct, and no corrections required.

The error lies in the second part of the sentence. We have to change 'country' to 'countries' to make the sentence meaningful. As per the rules of subject-verb agreement, the subject following the indefinite pronoun phrase 'one of the' is always a plural noun. The use of verbs as singular or plural will entirely depend upon the subject of the statement.
Hence, this option is the correct answer.

‘Lest' is a conjunction conveying negative meaning. It means 'to avoid the risk of'. Hence, further negation in the form of ‘no’ or ‘not’ is redundant. Change "...should not miss the train" to "... should miss the train".

The error lies in the first part of the sentence. We have to change "usual" to "ordinary" to make the sentence meaningful. 
'Usual' is used to refer to something happening frequently or normally. It is usually associated with events or occurrences. 'Ordinary'  is an adjective used to describe a natural state of an object. The sentence describes an ordinary thermometer. It does not have any specific equipment attached, and it is the typical instrument used to measure the temperature within a particular range.

As per the given question,

Games won $=13$

Games lost $=7$

Therefore, the total number of game played will be $=$ Games won $+$ Games lost $=\left(13+7\right)=20$

So,

win$\%=\frac{games won}{total games}\times 100\%$

$\Rightarrow \frac{13}{20}\times 100$

$\Rightarrow 65\%$

Hence, option B is the correct answer.

As per the given question,
$$\begin{gathered} 60\% of 35=x \% of 400 \\ \Rightarrow \frac{60}{100}\times 35=\frac{x}{100}\times 400 \\ \Rightarrow x=\frac{60\times 35}{400} \\ \Rightarrow x=\frac{2100}{400}=\frac{21}{4} \\ \Rightarrow x=5\frac{1}{4} \end{gathered}$$
Hence, option A is the correct answer.

As per the given question,

Number of people who will not get any prize will be $=\left(50-1\right)=49$

So, the required percentage will be,

$\Rightarrow \frac{matches lost}{total matches}\times 100$

$\Rightarrow \frac{49}{50}\times 100$

$\Rightarrow 98\%$

Hence, option D is the correct answer.

Let,
The total volume of air is $100$
So, The percentage of argon will be,
$\Rightarrow 100-(79.2+20.7+0.08)=0.02\%$
Let the volume of the air which contains one cubic metre of argon is $V$.
So,
$$\begin{gathered} \Rightarrow 0.02\% \mathrm{of} \mathrm{V} =1 \\ \Rightarrow \frac{0.02}{100}\times \mathrm{V}=1 \\ \Rightarrow \mathrm{V}= 5000 \mathrm{cubic} \mathrm{metre}. \end{gathered}$$
Hence, the correct option is D.

Let the total student appeared be $=x$

As per the question,

$\Rightarrow 49.3$ of $x=23128$

$\Rightarrow \frac{49.3}{100}\times x=23128$

$\Rightarrow 49.3x=23128\times 100$

$\Rightarrow 49.3x=2312800$

$\Rightarrow x=\frac{23128\times 100}{49.3}$

$\Rightarrow x=\frac{2312800}{49.3}$

$\Rightarrow 46912.77\approx 46913$

Hence, the correct option is A.

As per the question,
Price after raising price will be,
$\Rightarrow 50000+13000=63000$
As he deducted $\frac{1}{7}$ of the new price, So price after deduction will be,
$\Rightarrow (63000-\frac{1}{7}\times 63000)=₹54000$
So, the required percentage will be,
$$\begin{gathered} \Rightarrow \frac{54000}{50000}\times 100 \\ \Rightarrow 108\% \end{gathered}$$
Hence, the correct option is A.

Let the actual value of the chair is $= x$
So, the cost price will be $=(\frac{75}{100}\times x)=0.75x$
So, the selling price will be $=x+\frac{20x}{100}=1.2x$
Hence, the profit percentage will be
 $$\begin{gathered} \Rightarrow \frac{1.2x-0.75x}{0.75}\times 100 \\ \Rightarrow 60\% \end{gathered}$$
Hence, the correct option is B.

Let the selling price of item is $=x$
If there is $15\%$ loss on selling price.
Then the cost price will be
$=(x+\frac{15}{100}\times x)=1.15x$
So, the required loss percentage will be 
$$\begin{gathered} \Rightarrow \frac{1.15x-x}{1.15x}\times 100 \\ \Rightarrow \frac{0.15x}{1.15x}\times 100 \\ \Rightarrow 13.04\% \end{gathered}$$
Hence, the correct option is D. 

Let the M.P. of the article is $= x$
Discount will be
$\Rightarrow 4\% \mathrm{of} x= 0.04x$
So, the selling price will be
$\Rightarrow x-0.04x= 0.96x$
Given that, the selling price makes $10\%$profit on C.P.
Let C.P. of the article is $= y$
So,
$$\begin{gathered} \Rightarrow 1.1y= 0.96x \\ \Rightarrow y= 0.872x \end{gathered}$$
Therefore, required percentage added on the price of goods
$$\begin{gathered} \Rightarrow \frac{\mathrm{M}.\mathrm{P}.-\mathrm{C}.\mathrm{P}.}{\mathrm{C}.\mathrm{P}.}\times 100 \\ \Rightarrow \frac{x-y}{y}\times 100 \\ \Rightarrow \frac{x-0.872x}{0.872x}\times 100 \\ \Rightarrow 14.67\%= 14\frac{7}{12}\% \end{gathered}$$
Hence, the correct answer is option D. 

Let S.P. of the item $=x$

Profit percentage on S.P. $=25\%$

So, C.P. of item will be:

$\Rightarrow \left(x-\frac{25}{100}\times x\right)$

$\Rightarrow x-0.25x$

$\Rightarrow 0.75x$

Therefore, the required percentage will be

$\Rightarrow \frac{0.25x}{0.75x}\times 100$

$\Rightarrow 33\frac{1}{3}\%$

Hence, the correct answer is option C.

As  we know that,

Numerator of ratio is called antecedent while denominator is called consequent.

So, antecedent is $18$

$$\begin{gathered} \frac{18}{x}=\frac{2}{3} \\ x=\frac{18\times 3}{2}=27 \end{gathered}$$

So, number will be $\frac{18}{27}$

Let $?=\frac{x}{y}$

So,

$$\begin{gathered} \frac{2}{3}:\frac{5}{6}::\frac{8}{7}:\frac{x}{y} \\ \frac{{\displaystyle \frac{2}{3}}}{{\displaystyle \frac{5}{6}}}=\frac{{\displaystyle \frac{8}{7}}}{{\displaystyle \frac{x}{y}}} \\ \frac{2}{3}\times \frac{x}{y}=\frac{5}{6}\times \frac{8}{7} \\ \frac{x}{y}=\frac{10}{7} \end{gathered}$$

So, if A:B, B:C & C:D is given, then A:D can be calculated as,

 $$\begin{gathered} \frac{A}{D}=\frac{A}{B}\times \frac{B}{C}\times \frac{C}{D} \\ \frac{{\displaystyle A}}{{\displaystyle D}}=\frac{{\displaystyle 2}}{{\displaystyle 3}}\times \frac{{\displaystyle 4}}{{\displaystyle 5}}\times \frac{{\displaystyle 6}}{{\displaystyle 7}} \\ =\frac{16}{35} \end{gathered}$$

Thus, the ratio of A to D is $16:35$.

Let both the glasses are of $\text{'}x\text{'}$capacity.

So, in first glass,

Amount of milk will be $=0.33x$ 

Amount of water will be$=0.67x$

In second glass,

Amount of milk will be$=0.25x$

Amount of water will be$=0.75x$

If both are mixed,

Then the ratio of milk and water will be$=\frac{0.33x+0.25x}{0.67x+0.75x}=\frac{0.58x}{1.42x}=\frac{7}{17}$

As per question,

In $30$litre mixture,

Amount of milk will be $=\frac{7}{10}\times 30=21$ litre 

Amount of water will be $=\frac{{\displaystyle 3}}{{\displaystyle 10}}\times 30=9$ litre

Let water added $=x$litre in order to make this $3:7$

So,

$$\begin{gathered} \frac{21}{9+x}=\frac{3}{7} \\ =27+3x=147 \\ x=40 \end{gathered}$$ 

According to the question:

$40$ cattle graze a field in $60$ days

So, $1$ cattle can graze a field in

$\Rightarrow 60\times 40= 2400$ days

Thus, $1$ cattle graze double size field in

$\Rightarrow 2\times 2400= 4800$ days

Now, $x$ cattle graze double size field in

$\Rightarrow \frac{4800}{x}$ days

So, number of cattle will be:

$\Rightarrow \frac{4800}{x}= 40$

$\Rightarrow x= 120$ cattle
Hence, the correct answer is option A.

According to the question:
Subscription of A$= \mathrm{subscription} \mathrm{of} \mathrm{B}+700$
Subscription of B $= \mathrm{subscription} \mathrm{of} \mathrm{C}+300$
 Let, subscription by C $= x$
So, Subscription by B will be :
$\Rightarrow x+300$
And Subscription by A will be:
$\Rightarrow x+300+700= x+1000$
As per question:
$$\begin{gathered} \Rightarrow \mathrm{A}+\mathrm{B}+\mathrm{C}= 4700 \\ \Rightarrow \mathrm{x}+\mathrm{x}+300+\mathrm{x}+1000= 4700 \\ \Rightarrow 3\mathrm{x}+1300= 4700 \\ \Rightarrow \mathrm{x}= \frac{3400}{3}= 1133.33 \end{gathered}$$
Thus, Subscription by C will be:
$\Rightarrow ₹1133.33$
Subscription by B will be:
$\Rightarrow 1133.33+300= ₹1433.33$
Subscription by A will be:
$\Rightarrow 1133.33+1000= ₹2133.33$
So, Ratio of subscription of A, B and C will be:
$$\begin{gathered} \Rightarrow 2133.33 : 1433.33 : 1133.33 \\ \Rightarrow \frac{6400}{3} : \frac{4300}{3} : \frac{3400}{3} \\ \Rightarrow 64 : 43 : 34 \end{gathered}$$
So, profit ratio among A, B and C will be:  
$\Rightarrow 64 : 43 : 34$
Therefore, the profit share of A, B and C will be:
$$\begin{gathered} \Rightarrow \frac{34}{141}\times 846, \frac{43}{141}\times 846, \frac{64}{141}\times 846 \\ \Rightarrow ₹396, ₹270, ₹180 \end{gathered}$$
 Hence, the correct answer is option B.

According to the question:
As A, B, C invest capital for $12$ month,$7$ months and $5$ months respectively.
As the profit ratio among A, B, C is $4 : 2 : 3$
So, their share will be also in same ratio as per their profit ratio.
As per question:
A invest $₹1400$for $12$months.
Given that:
$$\begin{gathered} \Rightarrow A : B= 4 : 2 \\ \Rightarrow \frac{A}{B}= \frac{4}{2} \\ \Rightarrow \frac{1400\times 12}{B\times 7}= \frac{4}{2} \\ \Rightarrow B= \frac{1400\times 2\times 12 }{4\times 7}= ₹1200 \end{gathered}$$
Similarly, from B & C ratio:
$$\begin{gathered} \Rightarrow \frac{B}{C}= \frac{2}{3} \\ \Rightarrow \frac{1200\times 7}{C\times 5}= \frac{2}{3} \\ \Rightarrow C= \frac{1200\times 7\times 3 }{5\times 2} \\ \Rightarrow C= ₹2520 \end{gathered}$$
Hence, the correct answer is option A.

Let B's capital used for $y$ months
Let capital of A & B are $5x$ & $6x$ respectively.
And the profit ratio of A and B is $5 : 9$
Given that capital used for $8$ months:
So,
$$\begin{gathered} \Rightarrow \frac{5x\times 8}{6x\times y}= \frac{5}{9} \\ \Rightarrow 5x\times 8\times 9= 6x\times y\times 5 \\ \Rightarrow y=\frac{5x\times 8\times 9}{6x\times 5}= 12 \end{gathered}$$
Hence, the correct answer is option C.
 

Let the total profit $= x$
B's salary$= (120\times 12)= 1440$
So, net profit to be divided $= x-1440$
A and B equally gets
$\Rightarrow \frac{x-1440}{2}$
Share paid to A as an interest $\Rightarrow 10\% \mathrm{of} 22500= 2250$
Now, 
$$\begin{gathered} \Rightarrow \frac{\mathrm{B}\text{'}\mathrm{s} \mathrm{income}}{\mathrm{A}\text{'}\mathrm{s} \mathrm{income}}= \frac{{\displaystyle \frac{x-1440}{2}+1440-2250}}{\frac{x-1440}{2}+2250} \\ \Rightarrow \frac{1}{2}= \frac{x-3060}{x+3060} \\ \Rightarrow x= ₹9180 \end{gathered}$$
Hence, the correct answer is option C.

Let the missing number is $=x$

As per the question,

$$\begin{gathered} \frac{7+5+x+3+12}{5}=8 \\ 27+x=40 \\ x=13 \end{gathered}$$

Hence, the missing number is $13$.
