The data in Statement I alone are sufficient to answer the question, while the data in statements II alone are not sufficient to answer the question.4).

Answer»

From STATEMENT I:

Let the ratio of AGES Arbaaz and Salman be 2x and 5x respectively. 

From I and II:

5x - 2x = 18 

⇒ 3x = 18 

⇒ x = 6 years 

Arbaaz’s age = 6 × 2 = 12 years 

Salman’s age = 6 × 5 = 30 years 

Total ages of Arbaaz, Salman and Sohail at PRESENT = 30 × 3 = 90 - 15 = 75 years 

∴ Present age of Sohail = 75 - (30 + 12) = 33 years.

∴ Both statements are required to ANSWER the question.
