To find: The number of voters of age over 65 if the total number of voters is 596.

Summary: Find the percentage of voters of the given age group from the figure and the total is also given. Substitute the values in the equation and solve.

The total number of voters is 596. The percentage of voters of age over 60=25%

Percentage=value/total×100

value=percentage×total/100

Substitute the values in the equation, value=25×596/100=149; which is the number of voters of age over 60.

The circle graph is given below, If the total number of voters is 596, then the number of voters of age over 60 is 149.

**Page 53 Problem 11 Answer**

From the below given circle graph,

The percentage of voters of age 18−29=10%.

The percentage of voters of age 30−49=30%.

The number of people of age group 18−29 who voted is 45.

The percentage of voters of age 30−49 is three tomes the percentage of voters of age 18−29.

So in order to find the number of people of age 30−49 who voted, we need to multiply the number of people of age 18−29 who voted with three.

That is, 45×3=135. This is how Sahil calculated the answer, and he is correct.

Given the circle graph,

Knowing that the number of people of age 18−29 who voted is 45, Sahil said the number of people of age 30−49 who voted is 135.

He is correct. He did it by multiplying three to the number just like their percentages are got
