The difference between simple interest on a certain sum at the rate of 8% per annum for 18 months and 24 months is Rs 452. What is the sum (in Rs)?
Let the sum be = Rs. $$100x$$
Rate of interest = 8%
=> Simple interest = $$\frac{P\times R\times T}{100}$$
According to ques,
=> $$(\frac{100x\times8\times2}{100})-(\frac{100x\times8\times1.5}{100})=452$$
=> $$16x-12x=452$$
=> $$x=\frac{452}{4}=113$$
$$\therefore$$ Sum = $$100\times113=Rs.$$ $$11,300$$
