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.

The question demands Sumit's real salary. Not the increased one.
It clearly says " If the salary is increased" This means the answer has to be 34000. Isn't it?

Hello Everyone, can anyone please make me understand that.
If Sumit salary is 34000, then which must as the multiple of 3?
That means it must be something like as : 3x=34000.

R:S = 2x : 3x.
40:57cross {57*2:40*3} = 114:120.
(120-114)=6,
4000:4000cross{40*4000:57*4000} = 228000-160000 = 68000/6,

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

The ratio should be 38:55 not 40 : 57.

The ratio of students in class A and class B is 4:5. The ratio of the fee collected per student from class A and class B is 25:16. If the total fee collected is 81 lakh, what is the fee collected from class B. Can anyone solve this?

I took it as 2/5(x)+4000 and 3/5(x)+4000.
Am I right?
