What is the compound interest (in Rs) for 1 year on a sum of Rs 20000 at the rate of 40% per annum compounding half yearly?
1). 8000
2). 8650
3). 8750
4). 8800
.A = P $(1+\frac{(R1)^{}}{100})$ $(1+\frac{(R2)^{}}{100})$
= 10000 $(1+\frac{(10)^{}}{100})$ $(1+\frac{(12)^{}}{100})$
= $10000\times\frac{110}{100}\times\frac{112}{100}$
= Rs 12320
