1.	Sana deposited * 4000 in a bank for 1 – years. Thebank gives a half-yearly compound interest at 10%per annum. Find the compound interest,
Answer» For compound interestAmount = P(1 + R/100)^n = 4000(1 + 10/100)^n = 4000(11/10)^3 = 4(11)^3 = 41331 = 5324 Therefore,Compound interest= A - P= 5324 - 4000= Rs 1324

Sana deposited * 4000 in a bank for 1 – years. Thebank gives a half-yearly compound interest at 10%per annum. Find the compound interest,

Answer»

For compound interestAmount = P(1 + R/100)^n = 4000(1 + 10/100)^n = 4000(11/10)^3 = 4*(11)^3 = 4*1331 = 5324

Therefore,Compound interest= A - P= 5324 - 4000= Rs 1324
