What will be the compound interest of Rs. 8000 at 10% p.a. for 1 1/ 2 years. When compound interest is payable half yearly?

Correct Answer: Rs. 1261

Explanation:

Yearly interest = 10%
Half yearly = 5%
Time = 11/2 = (3/2) x 2 half yearly = 3 half yearly
Amount = 8000(1 + 5/100)3
= 8000 x (21/20)3
= 8000 x 21/20 x 21/20 x 21/20
= Rs. 9261
Compound interest = Amount - Principal = 9261 - 8000
= Rs. 1261
