Answer 1

6th

7th

Given: Percentage of females = 30%

Percentage of males = 40%

Total percentage of females and males = 30 + 40 = 70%

Percentage of children = Total percentage – Percentage of males and females

= 100% – 70%

= 30%

Hence, 30% are children.

8th

Total voters = 15,000

Percentage of voted candidates = 60%

Percentage of not voted candidates = 100 – 60 = 40%

Actual candidates, who did not vote = 40% of 15000

=\ \frac{40}{100}\times15000=6000= 10040×15000=6000

Hence, 6,000 candidates did not vote.

9th

Let Meera’s salary be Rs. x.

Now, 10% of salary = Rs. 400

> 10% of x = Rs. 400

\Rightarrow\ \frac{10}{100}\times x=400⇒ 10010×x=400

\Rightarrow x=\frac{400\times100}{10}⇒x=10400×100

\Rightarrow\ x=4000⇒ x=4000

Hence, Meera’s salary is Rs. 4,000.

10th

Number of matches played by cricket team = 20

Percentage of won matches = 25%

Total matches won by them = 25% of 20

= \frac{25}{100}\times2010025×20

= 5

Hence, they won 5 matches.
