Solution
Let principal amount = $Rs. P$
=> $C.I. = P [(1 + \frac{R}{100})^T - 1]$
=> $2,862 = P [(1 + \frac{12}{100})^2 - 1]$
=> $2,862 = P [(\frac{28}{25})^2 - 1]$
=> $2,862 = P (\frac{784 - 625}{625})$
=> $2,862 = P \times \frac{159}{625}$
=> $P = \frac{2,862 \times 625}{159}$
=> $P = 18 \times 625 = Rs. 11,250$
Let principal amount = $Rs. P$

=> $P = 18 \times 625 = Rs. 11,250$

At the end of 2 years, if you get 2862 total amount on one amount at interest rate of 12%, then what is the original amount
