Salaries of Ravi, Anil and Kavita are in the ratio 1 : 3 : 6. If their salaries are increased by 5%, 10% and 15% respectively, then what is the new ratio of their salaries?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 7 : 22 : 46
Each salary rises by its own percentage, so each term of the ratio is multiplied by its own factor (5% more means \(\times\frac{105}{100}\)), and the new terms are then reduced.
Ravi: \(1\times1.05=1.05\)
Anil: \(3\times1.10=3.30\)
Kavita: \(6\times1.15=6.90\)
New ratio \(=1.05:3.30:6.90=105:330:690\)
Dividing each term by 15: \(7:22:46\)
