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.

Why every one is taking this new ratio as 40/57 there may be a multiple for this i.e 40y/57y, here y is the multiple number other then x, can any one explain me about this, while doing cross multiplication it is important I think.

@Shalini I agree.
The question "What is Sumit's salary?" should be more clear.
-Is it Sumit's "present" salary?
-Or is it Sumit's "new" salary?
At first, I thought the question was asking for Sumit's "current" salary. The answer should be Rs. 34, 000.
But the given answer is Rs. 38, 000. That is Sumit's "new" salary (34, 000+4, 000) ("If" he got the raise) not Sumit's "present" salary as written in the explanation.

But how to you used the 2 for dividing the 68000.
This solution is out of the box.
Please explain me full solution, also explain how to used you 2 for dividing the 68000.

Hey, why can't we take Ravi's and Sumit's original salary as 1x and 2x respectively? Why only 2x and 3x?
