Question

Eight years ago Farah was five years older to Sahil. At present Farah is twice Sahil's age.
What is Farah's present age?​

Answer 1

Answer:

Let,

Farah's age be x

And

Sahil's age be y

Eight years ago :

Farah's age = x-8

Sahil's age = y-8

According to the question

x-8 = y-8+5 => x-8 = y-3 => x-5 = y ---- (i)

And x = 2y ---- (ii)

Substituting value of x in (i)

2y-5=y

y=5

Substituting value of y in (ii)

x = 2(5)

x = 10

Thus, Farah's present age is 10.
