The ratio of the age of P and Q is 8 : 5. After 6 years their age will be in the ratio of 3 : 2. Find the ratio of the sum and difference of the present ages of P & Q.

13 : 03 03 : 13 13 : 02 02 : 13

13 : 03

Ratio of age of P and Q = 8 : 5 (at present) Therefore,          (P + Q)    :      (P - Q) ⇒        (8 + 5)     :       (8 - 5) ⇒           13         :         3
