Question

The sum of the ages of 5 children born at the intervals of 4 years each is 65 years. What is the age of the eldest child?

Answer 1

Answer:

21 years old

Step-by-step explanation:

Let the youngest one be=x

So accordingly,

x

x+4

x+8

x+12

x+16

The eldest child here is x+16

According to the question,

x+x+4+x+8+x+12+x+16 = 65

5x+40=65

5x=25

x= 25/5 = 5

If x = 5 then the eldest child = x+16= 5+16 = 21

Extra: ALL THE CHILDREN; 5, 9, 13, 17, 21

HOPE THIS HELPS ^_^
