Question

find the compound interest on rupees 8000 for 1 and a half year at 10 % per annum interest being payable half-yearly​

Answer 1

Principal = Rs 8000  

Time = 1 1/2 yrs  

n = 3  

Rate = 10% p.a. = 5% half yearly  

 

So , Amount = P ( 1 + R/100 )^n  

= 8000 × ( 105 / 100 )^3  

= ( 8 × 105 × 105 × 105 ) / 1000  

= 9261 .  

 

So , Compound Interest = Rs 9261 - Rs 8000 = Rs 1261
