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 first difference of new ration is 17.
So, 34:51, 40:57,
Both ratio difference is 6.
6p=4000 than 51p=?
Answer is 34000. Now add given increased 4000.
So, 34000 + 4000 = 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?

Hai guys listen here...
the 2:3 ratio of Ravi & Sumith salary
2x:3x =>2x/3x
then
Salary increased by each 4000
2x+4000 ---------(1)
3x+4000----------(2)
let we write 2x+4000/3x+4000 (its become new ratio)
2x+4000/3x/4000=40/57 ratio
now solve this
57(2x+4000)=40(3x+4000)
114x+228000=120x+160000
114x-120x=228000-160000
6x=68000
now divided by 2
=> 3x=34000.
now we have 3x value is 34000
let subsitute equation no(2)
=>3x+4000
=>34000+4000
Ans =38000
ok bye...

@All.
The question makes no sense. Because both of their salaries might not be the same, it can be different. How come we put x both in their salaries?
Anyone, please explain to me.

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.

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.

57 - 40 = 17.
Then after.
57multiple with 4000 = 228000.
And then 40 multiple with = 160000.
Then substrate 228000-160000 = 68000.
Then 2x multiple 3x so 6x.
6x = 68000.
2x into 3x = 68000.
3x = 34000.
And then 3x+ 4000.
So 34000 + 4000 = 38000.
Then after.
57multiple with 4000 = 228000.
And then 40 multiple with = 160000.
Then substrate 228000-160000 = 68000.
Then 2x multiple 3x so 6x.
6x = 68000.
2x into 3x = 68000.
3x = 34000.
And then 3x+ 4000.
So 34000 + 4000 = 38000.

The original ratio of their salaries are 2:3 and they are increased by 4000 the new ratio is 40:57.
Let their salaries be 2x ,3x.
2x+4000:3x+4000 = 40 :57,
114x +228000 =120x +160000,
6x =68000,
3x =34000 sumits original salary is 34000,
And after increase his salary =34000 + 4000= 38000.
