ONLiNE UPSC · Accepted Answer

Let Aarav&rsquo;s current age = A
Then from Statement 1, his sister&rsquo;s age = A+15
From Statement 2:
In 6 years,
(A + 6) / (A + 15 + 6) = 4/5
A = 54 years
So, Aarav is 54 years old.
Therefore, both Statements are required to answer the question.
Hence, option c is correct.
