A. Rs. 17,000

B. Rs. 20,000

C. Rs. 25,500

D. Rs. 38,000

Answer: Option D

Solution(By Examveda Team)

Let the original salaries of Ravi and Sumit be Rs. 2x and Rs. 3x respectively
$${\text{Then}},\,\frac{{2x + 4000}}{{3x + 4000}} = \frac{{40}}{{57}}$$
⇒ 57(2x + 4000) = 40(3x + 4000)
⇒ 6x = 68,000
⇒ 3x = 34,000
Sumit's present salary
= (3x + 4000)
= Rs. (34000 + 4000)
= Rs. 38,000
