Frequently Asked Questions
Here we have provided some of the frequently asked questions related to this chapter:
Q1: If Chameli had ₹600 left after spending 75% of her money, how much did she have in the beginning?
A: Let the money with Chameli be ₹100
Money spent by her = 75% of 100
= 75/100 × 100 = ₹75
The money left with her = ₹100 – ₹75 = ₹25
₹25 are left with her out of ₹100
₹1 is left with her out of ₹100/25
₹600 will be left out of ₹100/25 × 600 = ₹2400
Hence, she had ₹2400 in beginning.
Q2: Find the ratio of the following:
(i) Speed of a cycle 15 km per hour to the speed of a scooter 30 km per hour
(ii) 5 m to 10 km
(iii) 50 paise to ₹5
(i) Speed of a cycle 15 km per hour to the speed of a scooter 30 km per hour
(ii) 5 m to 10 km
(iii) 50 paise to ₹5
A: i) Ratio of the speed of cycle to the scooter = 15/30 = 1:2
ii) Since 1 km = 1000m, so the required ratio is:
5m/10000m = 1:2000
iii) Since ₹1 = 100 paisa
₹5 = 500 paisa
So, the required ratio is 50 paise/500 paise = 1/10 = 1:10
Q3: Convert the following ratios to percentages.
(i) 3:4
(ii) 2:3
(i) 3:4
(ii) 2:3
A: i) 3:4 = 3/4 = 3/4 x 100/100 = 3/4 x 100% = 75%
ii) 2:3 = 2/3 = 2/3 x 100/100 = 2/3 x 100% = 66.6%
Q4: 72% of 25 students are good in mathematics. How many are not good in mathematics?
A: It is given that 72% of 25 students are good in mathematics.
Therefore,
Percentage of students who are not good in mathematics = (100 − 72)%
= 28%
∴Number of students who are not good in mathematics = 28/7 x 100
= 7
Thus, 7 students are not good in mathematics.
Q5: If 60% of people in a city like cricket, 30% like football and the remaining like other games, then what per cent of the people like other games? If the total number of people are 50 lakh, find the exact number who like each type of game.
A: Percentage of people who like other games = (100 − 60 − 30)%
= (100 − 90)% = 10 %
Total number of people = 50 lakh
Therefore, the number of people who like cricket = (60/100 x 50) = 30 lakh
Number of people who like football = (30/100 x 50) = 15 lakh
Number of people who like other games = (10/100 x 50) = 5 lakh
