The salaries of Ram, Tom and Gita are in the ratio of 4:5:7. If the increments in their salaries are 10%, 5% and 5% respectively, then what will be the new ratio of their salaries?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 88:105:147
Each salary grows by its own percentage, so the new salaries are found share by share and then compared.
Ram: \(4\times1.10=4.4\)
Tom: \(5\times1.05=5.25\)
Gita: \(7\times1.05=7.35\)
New ratio \(=4.4:5.25:7.35\). Multiplying by 20 to clear the decimals: 88 : 105 : 147
