# Calculate the Amount and Compound Interest on Rs 10800 for 3 Years at 12 1/2 % per Annum Compounded Annually - CBSE Class 8 - Mathematics

ConceptConept of Compound Interest

#### Question

Calculate the amount and compound interest on Rs 10800 for 3 years at 12 1/2 % per annum compounded annually.

#### Solution

Principal (P) = Rs 10, 800

Rate (R) =12 1/2% = 25/2 % (annual)

Number of years (n) = 3

Amount, A = P(1 + R/100)^n

= Rs [10800(1+ 25/200)^3]

= Rs [10800 (225/200)^3]

= Rs (10800 xx 225/200 xx 225/200 xx 225/200)

= Rs 15377.34375

= Rs 15377.34  (approximately)

C.I. = A − P = Rs (15377.34 − 10800) = Rs 4,577.34
