Question

Mr. Shekhar spends 60% of his income. From the balance he donates Rs. 300 to an orphanage. He is then left with Rs. 3,200. What is his income ?

Answer 1

Let Mr. Shekhar's income be Rs x.
Money spent = 60% of x = $\frac{60}{100}x$
Money donated in orphanage = Rs 300
Money left = Rs 3200
Money spent + Money donated + Money left = Total income
$$\begin{gathered} \Rightarrow \frac{60x}{100}+300+3200=x \\ \Rightarrow \frac{6x}{10}+3500=x \\ \Rightarrow x-\frac{6x}{10}=3500 \\ \Rightarrow \frac{4x}{10}=3500 \\ \Rightarrow x=8750 \end{gathered}$$
Thus, Mr. Shekhar's income is Rs 8750
