Question

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

Answer 1

hii friend 
let the granddaughter's age be x years . therefore grandfather's age will be 10x
according to the question
grandfather's age = granddaughter's age + 54
10x = x + 54
transposing x to L.H.S, we obtain:
10x - x = 54
9x = 54
x = 6
granddaughter's age = x years = 6 years
grandfather's age = 10x years = (10 x 6) = 60 years
hope u got it
pls mark it as brainliest answer plss

Answer 2

let the age of granddaughter be x.
then the age of grandfather be 10x.

given,
age of grandfather is 54 years more than the granddaughter

ATQ
10x=x+54.
10x-x=54
9x=54
x=54/9
x=6

therefore age of granddaughter=6years.
the age of grandfather =10×6=60years


hope it will help.....
