6. Grandfather's age is 4 times Abdul's age. Ten
years ago, his age was 7 times Abdul's age. Find
their present ages.​

Answer 1

Answer:

let the age of Abdul is x years

then his grandfather's age is 4x yr

10 years ago age of Abdul = x-10yr

10 years ago age of his grandfather =(4x-10)yr

According to question:-

7(x-10) = 4x-10

7x-70= 4x-10

7x-4x=-10+70

3x=60

x=60/3

x=20

present age of him=20yr

present age of his grandfather=20 X 4= 80 yrs
