Q:

The difference between the simple interest on a certain sum at the rate of 10%per annum for 2 years and compound interest which is compounded every 6 months is Rs.124.05. what is the principal sum

A) Rs.6000 B) Rs.8000
C) Rs.12000 D) none of these
 
Answer & Explanation Answer: B) Rs.8000

Explanation:

Compound Interest on P at 10% for 2 years when interest is compounded half-yearly

 

=P1+R21002T-P=P1+1204-P=P21204-P

 

Simple Interest on P at 10% for 2 years = PRT100=P×10×2100=P5

 

Given that difference between compound interest and simple interest = 124.05

 P*21204-P-P5=124.05

 

=>P21204-1-15=124.05

 P=8000
