Answer 1

Answer:

₹45,000  

Step-by-step explanation:  

Let x be the salary of the man.

Money spent on books =  $\frac{3x}{100}$

Leftover money = $\frac{97x}{100}$  

Money spent on groceries = $\frac{8}{100}$ × $\frac{97x}{100}$  

Leftover money = $\frac{92}{100\\}$ × $\frac{97x}{100}$= ₹ 40,158  

92 × 97x = 40158 × 10000

            x = $\frac{40158 * 10000}{92 * 97}$  

            x = ₹45,000

∴ The salary of the man is ₹45,000.
