Question

The grandfather's age in years is same to the grandsons age in months. The combined age of the grandfather and the grandson is 91. Find the age of both.

Answer 1

Answer: Grandfather's age= 84 years

grandson's age= 7 years

Step-by-step explanation:

As we know that:

1 year= 12 months

Let, Grandfather's age= x

Grandson's age= y

According To the statement,

x=12y

x-12y=0....(i)

Also it is given that x+y=91....(ii)

Subtract (i) from (ii)

We got, 13y=91

y=7

Put the value of y in (i)

x=12×7

x=84

Hence, x=grandfather's age i.e., 84 years and

y= grandson's age i.e., 7 years.
