Answer:
Correct Answer: 20 years
Step-by-step explanation:
According to the question
P+Q2=25
P + Q = 50 ......(i) (5 years ago)
P+Q+R3=25
P + Q + R = 75 ......(ii) (present age)
∴ Present age of P + Q = 50 + 10 = 60 years
Present age of R = 75 - 60 = 15 years
∴ Age of R after 5 years = 15 + 5 = 20 years
