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 |

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

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.

20*115/100 = 23,
30*110/100 = 33,
20*120/100 = 60.
23 : 33 : 60.
30*110/100 = 33,
20*120/100 = 60.
23 : 33 : 60.

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

110/100 = 1.1.
1.1 * 3 = 3.3.
1.1 * 3 = 3.3.

Take the original ratio numbers: 2 : 3 : 5
Multiply each by (1 + percentage increase in decimal form):
A → 2 × 1.15 = 2.3,
B → 3 × 1.10 = 3.3,
C → 5 × 1.20 = 6.
Remove decimals by multiplying by 10 → 23 : 33 : 60.

Why is that the amount of % is written as 115 instead of 15 ?

I still don't understand why we have written 115?

Hai @Asma, Try below:
Ans, is 10 years.
Say, present age is = X,
After 20 years man age will be 3X = X+20.
i.e, 3X = X+20.
3X-X = 20.
X = 10.
Results, the man present age is 10 years.
