Question

A's father is 35 years younger than his grandfather and 63 years older than him. the sum of the ages of all the three is 112 years. find the ages of each one of them.

Answer 1

Let A's age be x

Then A/Q

x+x+28+x+63=112

3x+91=112

3x=112-91

3x=21

x=21÷3

x=7

A's age =7 years

Answer 2

Answer: 7 years

Step-by-step explanation:

Let A's age be x

Then A/Q,

x + x + 28 + x + 63 = 112

3x + 91 = 112

3x = 112 - 91

3x = 21

x = 21 ÷ 3

x = 7

A's age = 7 years
