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.

Let the salaries of ravi&sumith 2x,3x
each salary increased by 4000.
i.e ((2x+4000)/(3x+4000))->1
new ratio is 40:57->2
from 1 &2 we get
6x=68000
3x=34000
salary of sumith = 34000+4000=38000
each salary increased by 4000.
i.e ((2x+4000)/(3x+4000))->1
new ratio is 40:57->2
from 1 &2 we get
6x=68000
3x=34000
salary of sumith = 34000+4000=38000

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
therefore,
3x=34000
for the simplication they have done this

You all have explained to get the salary of Summit's salary but, I need to know what is Ravi's? Can any one explain?

The shortcut formulae for these kinds of sums = (difference of new ratio/cross difference of both ratios )*increased value * require value.
= (57-40/120-114) * 4000 * 3.
= 17/6 * 12000.
=34000 =34000 + 4000(given in the question).
= (57-40/120-114) * 4000 * 3.
= 17/6 * 12000.
=34000 =34000 + 4000(given in the question).

The Salaries of Yasmeen and Adnan are in the ratio 1 : 2. If the salary of each is increased by Rs. 3000, the new ratio becomes 40 : 57. What is Adnan's present salary? Please solve this.

Please tell me. How 114x -120x = 228000 - 160000 becomes 6x = 68000 instead of -6x = 68000?
I think, it should be 114x - 120x = -6x.
I think, it should be 114x - 120x = -6x.
