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 |

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

Why we have to use K there and how 15% is changed to 115?

15% increase in salary = (100+15)% of 2k = (115/100)*2k.

115*2/10=23,
110*3/10=33,
120*5/10=60.
So, 23:33:60.
110*3/10=33,
120*5/10=60.
So, 23:33:60.

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