Question

Suresh spends 80% of the money that he receives every month and saves RS 1200. How much money does he get monthly?​

Answer 1

$\sf Let \: the \: monthly \: income \: be \:₹ \: x \\ \\ \sf \: Savings \: = \: ₹ \: 1200 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\sf \: Expenditure \: = \: 80\% \: of \: x \: = \: \frac{80}{100} \: \times \: x \: = \: \frac{8x }{10}$

$\color{deeppink} \boxed{ \sf \: Savings \: = \: Total \: monthly \: salary \: - \: Expenditure}$

$\sf \: x \: - \: \frac{8x}{10} = 1200 \\ \\ \sf \: x \: = \: 6000 \: \: \: \: \: \: \: \:$

$\color{aqua}\sf \: Thus, \: the \: monthly \: salary \: of \: Suresh \: is \: ₹\:6000.$
