7. In a city, 30% are females, 40% are males and the remaining are children. What percent are children?8. Out of 15,000 voters in a constituency, 60% voted. Find the percentage of voters who did not vote. Can you now find how many actually did not vote?

7. Given: In a city 30% are females and 40% are males and the remaining are children.

To find: We have to find the percent of children in the city.

Solution: 

Total percent = 100%

Females = 30%

Males = 40%

So,

Children = 100% - (30% + 40%)

Children = 100% - 70%

Children = 30%

8. Given: Out of 15000 voters in the constituency, 60% voted.

To find: We have to find the actual number and percentage of people who did not vote.

Solution: 

Total % Voters = 100%

% of voters who voted = 60%

% of voters who did not voted = 100% - 60% = 40%

Now,

Number of voters did not vote = 40% of 15000

Number of voters did not vote = $\frac{40}{100} \ \times 15000$

Number of voters did not vote = 40 x 150

Number of voters did not vote = 6000
