Practice questions on Data Sufficiency - Ages — with answers

Try each question first, then open the answer. Explanations are included.

1. How old is Rajesh? Statement I: The sum of Rajesh's and Nisha's age is 259 years. Statement II: The ratio of Nisha's age to Mohan's age is 5:7.

  1. AStatement I alone is sufficient to answer the question, while Statement II alone is not sufficient
  2. BStatement II alone is sufficient to answer the question, while Statement I alone is not sufficient
  3. CBoth statements together are sufficient to answer the question, but neither statement alone is sufficient
  4. DBoth statements together are not sufficient to answer the question
Show answer

Answer: D

Statement I gives only the combined total of Rajesh and Nisha (two unknowns, not sufficient alone). Statement II relates Nisha and Mohan, neither of which pins down Rajesh's age on its own. Even combining both statements, Rajesh's age cannot be uniquely determined, since the information about Mohan does not connect back to Rajesh. Hence both statements together are not sufficient.

2. What is Amit's present age? Statement I: The sum of Amit's and Bina's age is 299 years. Statement II: The ratio of Bina's age to Chetan's age is 2:7.
