5 years ago, the average age of P and Q was 15 years. Average age of P, Q and R today is 20 years. How old will R be after 10 years?
- Solution: Five years ago, the average age of P and Q was 15, making their combined age 30.
- Fast forward to today, they've both aged 5 years, so their total age now is 40.
- Meanwhile, the current average age of P, Q, and R is 20.
- This makes their total age 60.
- Thus, R's present age must be 20 because 60 minus the combined ages of P and Q (40) equals 20.
- Looking ahead a decade, R will be 30 years old.
- Hence, the correct answer is (D) 30 years.
