Question

the present age of a grandfather is 4 times of his grandson. after 10 years the age of grandfather will become 3 times the age of his grandfather son .find their present ages

Answer 1

Answer:

grandson age = 20

grandfather age = 80

Step-by-step explanation:

let the present age of grandson be = x

present age of grandfather will be = 4x

after 10 years

age of grandson = x + 10

age of grandfather = 4x + 10

it is given that after 10 years grand father age will be 3 times that of grandson

3(x + 10) = 4x + 10

3x + 30 = 4x + 10

4x - 3x = 30 - 10

x = 20

present age of grandson = x = 20

present age of grandfather = 4x = 4 × 20 = 80
