Find the amount and the compound interest. Principal ₹ Rate (p.c.p.a.) Duration (years) 2000 5 2

Compound interest is calculated based on the principal, interest rate and the time involved as follows: If P is the principal (the initial amount you borrow or deposit), r is the annual rate of interest, n is the number of years the amount is deposited or borrowed for and, A is the amount of money accumulated after n years, including interest, then, the amount A is given by, A = p 1 + r 100 n . Here, p = ₹ 2000 , r = 5 % and n = 2 years. So, we get, A = ₹ 2000 × 1 + 5 100 2 ⇒ A = ₹ 2000 × 1 + 1 20 2 ⇒ A = ₹ 2000 × 21 20 2 ⇒ A = ₹ 2000 × 441 400 ⇒ A = ₹ 5 × 441 ⇒ A = ₹ 2205 . Now, we have, the compound interest = amount - principal = A - p = ₹ 2205 - ₹ 2000 = ₹ 205 . Therefore, the required amount is ₹ 2205 and the compound interest is ₹ 205 .
