Answer 1

grandson age=x
man=10x
10x=x+54
10x-x=54
9x=54
x=54/9
x=6
grandson =6years
man=10x= 10(6) =60 years

Answer 2

Hello!

Let,

✓ Grandson's present age be = x
✓ Grandfather's present age be = 10x

Then,

x = 10x - 54

⇒ 10x - x = 54

⇒ 9x = 54

⇒ x = 54 / 9 ⇒ x = 6 

Therefore,

✓ Grandson's present age = 6 years
✓ Grandfather's present age = 10 ( 6 ) = 60 years

Cheers!
