Question

The ratio of income to expenditure of a family is $7:6$.Find the savings if the income of family is $Rs.42000$ ?

Answer 1

Ration of Income and expenditure

$7:6$

Suppose Income is $7x=4200$

expenditure is 6x

$7x=42000$

$x=\frac{42000}{7}$

$x=6000$

expenditure $=6x$

$=6\times 6000$

$=36000$

saving = Income - expenditure

$=42000-36000$

$=6000$ Answer
