Answer 1

$\bf \huge {\underline {\underline \red{AnSwEr}}}$

⠀⠀⠀⠀⠀⠀

Given

⠀⠀⠀⠀⠀⠀

• Ratio of income and expenditure of certain family = 9 : 7

⠀⠀⠀⠀⠀⠀

• Income = 45000

⠀⠀⠀⠀⠀⠀

To Find

⠀⠀⠀⠀⠀⠀

• Expenditure = ?

⠀⠀⠀⠀⠀⠀

Solution

⠀⠀⠀⠀⠀⠀

Let Income be 9x and expenditure be 7x.

⠀⠀⠀⠀⠀⠀

Income :-

⠀⠀⠀⠀⠀⠀

$\bf \implies 9x = 45000$

⠀⠀⠀⠀⠀⠀

$\bf \implies x = 45000 \div 9$

⠀⠀⠀⠀⠀⠀

$\bf \implies x = 5000$

⠀⠀⠀⠀⠀⠀

$\bf \implies Expenditure = 7x$

⠀⠀⠀⠀⠀⠀

$\bf \implies 7x = 7 \times 5000$

⠀⠀⠀⠀⠀⠀

$\bf \implies 35000$

⠀⠀⠀⠀⠀⠀

Therefore, Expenditure is Rs. 35000.
