Question

Six years ago the average ages of 'P' and 'Q' was 16. The present average ages of 'P', 'Q' & 'R' is 25, then after 15 years, what will be the age of 'R'​

Answer 1

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

Answer 2

Answer:

24

Step-by-step explanation:

p+q=16,

p+q+r=25

16+r=25

r=9

9+15
