Answer 1

Answer:

Let Granddaughter's present age be x

Then, Grandfather's age = 10x

Given,

Grandfather's age = Granddaughter's age + 54

10x = x + 54

10x - x = 54

9x = 54

X = 54

x = 6

Answer 2

Question :

A grandfather is ten Times older than his granddaughter. He is also 54 years older than her. Find their persent age?

Solution :

Age of granddaughter be x

Age of grandfather 10 years

According to the Question :

• x + 54 = 10 x

• x - 10 x = - 54

• - 9x = - 54

• x = 6

Age of grand daughter = x = 6 years

Age of grandfather = 10x = 10 × 6 years = 60 years
