[D].
Answer: Option C
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 |
