Question :

Ratio of Income and expenditure of a man is 7:4 and his income is 3500,find his expenditure and savings .

Answer :

$\sf\pink{Given:}$

• Ratio of income to expenditure is 7:4 .

• Income is 3500 .

$\sf\pink{To\:find:}$

• his expenditure ?

• his savings ?

Explanation :

• let his expenditure be "x"

$\\ \longrightarrow\sf{\dfrac{7}{4} = \dfrac{3500}{x}}$

$\\ \longrightarrow\sf{7\times x = 4\times 3500}$

$\\ \longrightarrow\sf{7x = 14000}$

$\\ \longrightarrow\sf{x = \dfrac{14000}{7}}$

$\\ \longrightarrow\sf{x = 2000}$

• Therefore his expenditure is 2000 .

Savings = Income - Expenditure

$\\ \longrightarrow\sf{ 3500 - 2000}$

$\\ \longrightarrow\sf{ 1500 }$

• Therefore his savings is 1500
