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?
Answer: Option
Explanation:
Let the original salaries of Ravi and Sumit be Rs. 2x and Rs. 3x respectively.
| Then, | 2x + 4000 | = | 40 |
| 3x + 4000 | 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.

@Shikha.
Its just the new ratio. Read the question again and look at the 1st explanation til the 3rd step.
After that just divide 68000 by 6. You will get 33999 and it rounded of to 34000.
34000+4000 = 38000 which means 34000 was his old salary and aft increment of 4000 he gets 38000.

@Shikha.
40/57 is the new ratio. Read the question twice, you will get it.
