Question

A grandfather is ten times older than his granddaughter. He is also 54 years older than her. Find their present ages​

Answer 1

let granddaughter's age be x.

hence,

grandfather's age = 10x

also given that,

10x = 54 + x

10x - x = 54

9x = 54

x = 54/9

x = 6

Therefore, granddaughter's age = 6 yrs

                  grandfather's age = 10(6) = 60 yrs

Hope this helps!!

Pls mark me as brainliest!!
