Salaries of Ravi and Sumit are in the ratio 2 : 3. If the salary of each is increased by Rs. 4000, the new ratio becomes 40 : 57. What is Sumit's salary?
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
