Answer 2

Answer:

present age of grandfather = 60 years

present age of granddaughter = 6 years

Step-by-step explanation:

Let the present age of granddaughter be Y

so, the age of grandfather = 10Y

A.T.Q.

10Y = 54 + Y

10Y - Y = 54

9Y = 54

Y = 54 ÷ 9

Y = 6

so , therefore , present age of granddaughter = Y = 6 years

and , present age of grandfather = 10Y = 10 × 6 = 60 years
