Question

The ratio of the income to the expenditure of a family is 7 : 6. Find the saving if the income is Rs 1400.

Answer 1

The ratio of the income to the expenditure of a family is 7 : 6.

$\therefore$ Ratio of saving to the income = (7 $-$ 6) : 7 = 1 : 7 (Saving = Total income $-$ Expenditure )

$\because$ Income of the family = ​Rs. 1400

$\therefore$ Saving = $1400\times \frac{1}{7}=\mathrm{Rs}.200$
