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.

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.
If Sumit salary is 34000, then which must as the multiple of 3?
That means it must be something like as : 3x=34000.

114x+4000*57=120x+4000*40.
6x = 4000(57-40),
6x = 4000*17,
x = (4000*17)/6,
Now you want to Sumit salary which is 3x in the above question.
3* (4000*17)/6 = 34000=> answer.
6x = 4000(57-40),
6x = 4000*17,
x = (4000*17)/6,
Now you want to Sumit salary which is 3x in the above question.
3* (4000*17)/6 = 34000=> answer.

2:3 difference is 1.
40:57 difference is 17.
Cross multiply:
{2:3 * 17} 34:51.
{40:57 * 1}40:57.
Then difference of 2 ratios is 6.
6=57*4000,
6=228000,
228000÷6,
38,000.
40:57 difference is 17.
Cross multiply:
{2:3 * 17} 34:51.
{40:57 * 1}40:57.
Then difference of 2 ratios is 6.
6=57*4000,
6=228000,
228000÷6,
38,000.

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.

It is stated in question 'if' the salary is increased but it is not actually increased now at present how at the last point you have added 3x+4000?
Anyone, explain please.

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,

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?

Yes, it has another method.
2:3
40:57 -> difference = 17.
Cross multiply it,
(17/6)*4000*3=34000.
Total=34000+4000=38000.
114:120 ->difference = 6.
2:3
40:57 -> difference = 17.
Cross multiply it,
(17/6)*4000*3=34000.
Total=34000+4000=38000.
114:120 ->difference = 6.

Just they have splitted the term
6x=68000
we can also write it as
2*3x=68000
3x=68000/2
therefore,
3x=34000
for the simplication they have done this
6x=68000
we can also write it as
2*3x=68000
3x=68000/2

R/S = 2/3.
(R+4000) / (S+4000) = 40/57.
Putting the value of are = (2/3) S,
And get value s = 34000.
What is wrong in this? Please explain it.
