• A. 400
• B. 500
• C. 600
• D. 750

Answer 1

Answer:

B. 500

Solution:

Let the monthly income of a man is 100x

He spends 15% of his income.

ie., 15% of 100x= $\frac{15}{100}\times{100x}=15x$

which is equal to 75 Rs.

$15x=75$

$x=\frac{75}{15}$

$x=5$

Monthly income of a man $= 100x=100\times{5}=500Rs.$
