Answer 2

Answer:

Amount will be $\bold{\left(x^{3} / 100\right)+X}$

Explanation:

P= principle = X and R= rate = X% and T = time = X  

So the (S.I) = R x P x T/100 [simple interest]

Amount = S.I + P  

S.I = R x P x T/100 = (X x X x X) /100  

So the $\mathrm{S.I}=\mathrm{x}^{3} / 100$

Therefore Amount = S.I + P = $\left(x^{3} / 100\right)+X$

By solving the equation we will get the amount = $\left(x^{3} / 100\right)+X$
