Question

The ratio of monthly income to the savings of a family is 11 : 2. If the savings be Rs 2500, find the income and expenditure.

Answer 1

Suppose that the monthly income of the family is Rs x.

Then, x : 2500 = 11 : 2

⇒ x = $\frac{11\times 2500}{2}=11\times 1250$
⇒ x = Rs 13750

Hence, the income is Rs 13,750.
∴ Expenditure = (monthly income − savings)
=Rs (13750 − 2500)
= Rs 11250
