Question

An uncle is older than his nephew by 10 years. Fifteen years ago, uncle was twice as old as his nephew. What are their respective ages.​

Answer 1

Answer:

Sum of their ages 10 years ago was 60

Step-by-step explanation:

Sum of their ages 10 years ago was 60

So, ten years later (present), the sum of their total ages

60 + 10 + 10 = 80

Uncle is now 4 times as old as nephew

So, there are 5 equal parts altogether

80 ÷ 5 = 16 (nephew's age)

Uncle is 4 times as old as nephew

16 × 4 = 64

Ans. Sum of their ages 10 years ago was 60
