Question

A grandfarther is ten times older than its granddaughter. He is also 54 years older than her. find their present age?

Answer 1

If grandfather's old= x
granddaughter's old = y

So, 10y= x
=> 10y = 54 [x=5]
=> y = 54÷10
=> y = 5.4

Now, x+y = 54+5.4
= 59.4 [Answer]

Answer 2

Let granddaughter age =x
Grandfather age =54
Granddaughter age =54/10
