Ravi took a loan of certain amount from a bank. If the difference of compound interest and simple interest on that amount for 3 years at the rate of 5% per annum is Rs. 11.40, then the amount is
1). Rs. 1500
2). Rs. 1475
3). Rs. 1395
4). Rs. 1495
We know that,
S.I. = Simple interest
C.I. = Compound interest
P = Principal amount
R = interest rate
T = time
CI - SI = P(R/100)2(R/100 + 3)
∴ P = [(CI - SI) × (100)3/{(R)2 × (300 + R)}]
⇒ (11.4 × (100)3)/{(5)2 × (300 + 5)}
⇒ Rs. 1495
