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.

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

4000 should not be added because the question is if it increases, not increased. So, answer is 34000.

@Basu.
Here;
6 represents the difference 4000.
Therefore 4000 ÷ 6*57=38000.

How we get 2x+4000/3x+4000 = 47/50?
and why not 2x+4000/3x+4000 = 47x/50x?
and why not 2x+4000/3x+4000 = 47x/50x?

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

My question is why can't we find the value of x, and then multiply by 3.
