• A. $Rs.11,500$
• B. $Rs.11,000$
• C. $Rs.10,000$
• D. $Rs.10,500$

Answer 1

The correct option is D $Rs.10,500$

Let Pratap's salary $=Rs.x$

Money left with him after paying the tax $=8400$

Percentage of salary he paid $=20$%

Percentage of salary is left with=$100\%-20\%$

$=80$%

Therefore,

$80$% of $Rs.x=8400$

$\frac{80}{100}\times x=8400$

$x=\frac{8400\times 100}{80}$

$x=10500$

Thus,

Pratap's salary $=Rs.x=10500$

Hence, this is the answer.
