Rajiv invested a certain sum of money at 10% per annum. After 2 years, he received ₹199.5 as compound interest, compounded annually. Find the corresponding simple interest (in ₹) for 2 years at the same rate.
190
Compound interest for 2 years at 10%: \(P\left[(1.1)^2-1\right] = 199.5 \Rightarrow P\times0.21 = 199.5 \Rightarrow P = 950\).
Simple interest for 2 years at 10%: \(950\times0.1\times2 = 190\).
Hence, the corresponding simple interest for 2 years is ₹190.
