Question

the ratio in income to expenditure of a family is 7:6 .Find the savings if the income of family is $4200​

Answer 1

Answer:

The savings of the family, if the income is $4200, is $600.

Step-by-step explanation:

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

That means, if the income is $7x$, then the expenditure is $6x$.

The income of the family is $4200.

Hence the value of $x$ is obtained by solving the following equation.

$7x=4200\\\\x=\dfrac{4200}{y=7}=600$

So,

$6x=6\times 600= 3600$

Expenditure is $3600.

Hence savings is $4200-$3600 = $600
