• B. Rs. $100$x
• C. Rs. $\left(\frac{100}{x}\right)$
• D. Rs. $\left(\frac{100}{x^2}\right)$

Answer 1

Answer: (C)

Rs. $\left(\frac{100}{x}\right)$

Let sum is $P$.

Simple interest will be $\frac{P\times x\times x}{100}$

Given simple interest is $x$

$\Rightarrow x=\frac{P\times x\times x}{100}$

$\Rightarrow P=\frac{100}{x}$
