Dhoni’s income is 10% more than Rohit’s income. Correct Answer Only I

From statement I: 

Let the income of Virat’s wife be Rs. x per month.

∴ According to the statement

⇒ 0.05x = 975 

⇒ x = 19500/- 

∴ Virat’s income is 70% of x = 19500 × 70/100 = Rs. 13650

But Rohit’s income can’t be calculated from statement II and III. 

∴ Statement I is sufficient to answer the question.
