Question

a grandfather is 10 times older than his granddaughter he is 54 years older than her find age of granddaughter

Answer 1

Let granddaughters age be 'x'.

According to the question,

Grandfather's age = 10x = x + 54

=> 10x = x + 54

=> 10x - x = 54

=> x = 54/9

=> x = 6

Therefore age of granddaughter = 6 years

And age of grandfather = 60 years.

Answer 2

Hey mate!!!
here's the answer...

Let granddaughter's age be = x
then grandfather's age will be = 10x
according to the question 10x = x + 54

Equation will be:-
10x = 54 + x
10x - x = 54
9x = 54
x= 54 / 9
x= 6

So granddaughter's age is 6 years
and grandfather's age will be 60 years
