Question

Amina's father is 28 years younger than Amina's grandfather and 31 years older than Amina.
The sum of the ages of all three is 153 years. What is the age of each one of them.​

Answer 1

Step-by-step explanation:

let x be the age of Amina's father

therefore , Amina's grandfather = x+28

and Amina's age = x-31

From question we also have

sum of the ages of all three= 153

x+(x+28)+(x-31) = 153

3x- 3 = 153

3x= 153+3

x= 156/3 = 52

therefore Amina's father age = 52 years

and Amina's grandfather age= x+28 = 80 years

and Amina's age = x-31 = 21 years
