Answer :
a. The villagers that are over 60 are 100
b. 15% of the villagers are under 25
A First, we have to know that percentage is the quotient of a number and hundred. It is represented with the sign '%'
Now, from the information given, we have that;
The number of villagers = 200 people
From the chart, half of the villagers are over 60
50% of 200
50/100 × 200
= 100 people
b. 15% of the villagers are under 25
15/100 × 200
Multiply the value
40
