Correct Answer:
A. 23:33:60
To find the new ratio, we first calculate the new salary for each person based on their initial ratio and percentage increase.
- Let the initial salaries of A, B, and C be 2x, 3x, and 5x respectively.
- New salary for A: 2x * (1 + 0.15) = 2x * 1.15 = 2.3x
- New salary for B: 3x * (1 + 0.10) = 3x * 1.10 = 3.3x
- New salary for C: 5x * (1 + 0.20) = 5x * 1.20 = 6.0x
The new ratio is 2.3x : 3.3x : 6.0x. To eliminate decimals and simplify, multiply each term by 10, resulting in 23:33:60. Distractors B, C, and D result from incorrect percentage calculations or errors in simplifying the ratio.
