The ratio of the income and expenditure of a person is 11 : 10, and he saves ₹9,000 per year. What is his monthly income?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → ₹8,250
Saving is income minus expenditure. With income and expenditure in the ratio 11 : 10, the saving is the difference of one part.
Assuming the yearly income to be \(11x\) and the expenditure \(10x\):
Saving \(=11x-10x=x=9000\)
Yearly income \(=11\times9000=99000\)
Monthly income \(=99000\div12=8250\)
