The salaries of A, B and C are in the ratio 2 : 3 : 5. If their respective salaries are increased by 15%, 10% and 20%, find the new ratio of their salaries.

Explanation

Original salaries are in the ratio 2 : 3 : 5. After increases of 15%, 10% and 20%:

2(1.15) : 3(1.10) : 5(1.20) = 2.3 : 3.3 : 6

Multiply by 10 → 23 : 33 : 60.
