The salaries A, B, C are in the ratio 2 : 3 : 5. If the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be new ratio of their salaries?
Answer: Option
Explanation:
Let A = 2k, B = 3k and C = 5k.
| A's new salary = | 115 | of 2k = |  |
115 | x 2k |  |
= | 23k |
| 100 | 100 | 10 |
| B's new salary = | 110 | of 3k = | |
110 | x 3k | |
= | 33k |
| 100 | 100 | 10 |
| C's new salary = | 120 | of 5k = | |
120 | x 5k | |
= 6k |
| 100 | 100 |
 New ratio |
|
23k | : | 33k | : 6k | |
= 23 : 33 : 60 |
| 10 | 10 |

@Mankandan :
We can also use x instead of k.
15% is changed to 115 it is a shortcut method to avoid long caluclation.

It can be solve in ay method:
2 * 115 : 3 * 11 : 5 * 120.
= 2 * 23 : 3 * 22 : 5 * 24.
= 23 : 33 : 60.
2 * 115 : 3 * 11 : 5 * 120.
= 2 * 23 : 3 * 22 : 5 * 24.
= 23 : 33 : 60.

New ratio of their salaries,
115*2=230.
110*3=330.
120*5=600.
i.e 230:330:600.
i.e 23:33:60.
115*2=230.
110*3=330.
120*5=600.
i.e 230:330:600.
i.e 23:33:60.

Why the 10 and x gets cancelled in above question of Ratio and Proportion?

Why you take 115/100 of 2k instead of 2k+15%? Please explain more in simplest form.

115/100*20:110/100*30:120/100*50.
= 23:33:60.
Here 2=20 and 3=30 and 5=50.
= 23:33:60.
Here 2=20 and 3=30 and 5=50.
