You have to decide whether the date given in the statements is sufficient to answer the question or not.Solution
Rohit + Dhawan+ Virat + Dhoni + Mayank= 28 × 5 = 140 From statement I: Dhawan+ Virat + Dhoni + Mayank= 112 From statement II: Dhawan = Mayank – 6 and Mayank = Dhoni – 10 so, Dhoni = Mayank + 10 From statement III: Virat = Dhawan + 12 and Mayank + 6 ;Combining all three statements, we get the age of Virat.
