An amount invested at simple interest gives Rs 2550 interest at rate of 17% per annum in 3 years. What is the principal (in Rs)
Let the principal be = Rs. $$100x$$
Rate of interest = 17% and time period = 3 years
Simple interest = $$\frac{P\times R\times T}{100}$$
=> $$\frac{100x\times17\times3}{100}=2550$$
=> $$51x=2550$$
=> $$x=\frac{2550}{51}=50$$
$$\therefore$$ Principal sum = $$100\times50=Rs.$$ $$5000$$
=> Ans - (B)
