Answer 1

Answer:

(c) Rs. 1500

Step-by-step explanation:

Percentages

It's given Kamal spent 40% of his income. With the remaining 60%, he deposited Rs. 400 in a bank and still has Rs. 500 left.

This means Rs. 400 + Rs. 500= Rs. 900 is 60% if his income.

The 100% of his income is calculated as a percent proportion:

If 60% is Rs. 900, then 100% is:

$\displaystyle \frac{900}{60}*100=1500$

Thus, Kamal's income is Rs. 1500. Correct choice: (c) Rs. 1500
