Question 111

The ratio between the present ages of P and Q is 3:4 respectively.Four years hence Q will be five years older than P.What is P’s present age ?

Solution

Let P/q= 3/4, 4 years from hence means adding 4 to present ages of both p,q .

Also q is 5 years bigger than p after 4 years. so, p+9= q+4.

we already have p/q=3/4 or 3q=4p,

so, q=4/3p ,

p+9=4/3p+4,

p/3=5, so Solving for P we get 15.
