The ratio of present ages of P and Q is 1: 3. The present age of P is 3 times the present age of R. Sum of the present age of P, Q and R is 65 years. Find the present age of Q?
A45
B42
C40
D39
Answer:
A. 45
Read Explanation:
The ratio of present ages of P and Q = 1: 3 (x, 3x)
P = 3R
R = x/3
P + Q + R = 65
x + 3x + (x/3) = 65
13x/3 = 65
13x = 65*3
x = 15
Present age of Q = 3x = 45 years
