Question

The ratio of income to savings of a family is 11 : 2. Find the expenditure if the savings is Rs 1520.

Answer 1

Income:Savings = 11:2
Let the income and the saving be Rs 11x and Rs 2x, respectively.
Saving = Rs 1520
2x = 1520
x = 1520 = 760
2
$\therefore$ Income = Rs 11x =Rs (11 × 760) = Rs 8360
Expenditure = Income $-$ Saving
= Rs (8360 $-$ 1520 )
= Rs 6840
