Question 144

The sum of the present ages of P and Q is 25 years more than the age of R. The present age of Q is 5 years more than that of R. Find the present age of P

Solution

Let present ages of P,Q and R be $$p,q,r$$ years respectively.

=> $$q = r + 5$$ ------------(i)

and $$p + q = r + 25$$ ------------(ii)

Subtracting eqn(i) from (ii), we get :

=> $$p = 25 - 5 = 20$$

$$\therefore$$ Present age of P = 20 years
