Question

a man spends 85 % of his monthly salary. if he saves Rs.450 per month , what is his monthly salary?

Answer 1

Let the monthly salary = Rs. x
percentage of expenditure = 85 %
so, percentage of saving = (100 - 85)% = 15 %
$$\begin{gathered} \mathrm{now},15\%ofx=450 \\ \Rightarrow \frac{15}{100}\times x=450 \\ \Rightarrow x=\frac{450\times 100}{15}=3000 \\ \mathrm{so}\mathrm{monthly}\mathrm{salary}=\mathrm{Rs}.3000 \end{gathered}$$
