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.

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.
