The question is accompanied by three statements (A), (B) and (C). You have to determine which statement(s) is/are sufficient/necessary to answer the question.
What is the ratio of the present ages of X and Y?
A. The ratio between the present ages of X and Y after 10 years is 11:15.
B. The present age of Y is 200/3 % more than that of X.
C. The product of the present ages of X and Y is 240 years.

• A. Any of them
• B. Only C and either A or B
• C. Any two of them
• D. Only A and B together

Answer 1

Answer: (B)

Only C and either A or B

Answer 2

By Using B and C together, we can form two equations to solve for their present ages and the ratio. A is not strictly necessary as B and C provide enough information.

The correct option is (B): Only C and either A or B
