Question

If the ages of P and R are added to twice the age of Q, the total becomes 59. If the ages of Q and R are added to thrice the age of P, the total becomes 68 and if the age of P is added to thrice the age of Q and thrice the age of R, the total becomes 108. What is the age of P?

• A. 19 yr
• B. 15 yr
• C. 17 yr
• D. 12 yr

Answer 1

The Correct Option is D

According to question
P+R+2Q=59...........1
Q+R+3P=68 .........2
P+3Q+3R=108 .................3
Multiply equation (2) by 3
And subtract equation (iii) from it,
Then P=12 years.
So the correct option is (D)
