MCQ

The difference between Simple Interest and Compound Interest on Rs. 500 for 1 year at 10% per annum, reckoned half-yearly is

• Rs. 1

• Rs. 1.25

• Rs. 1.5

• Rs. 2

#### Solution

Rs. 1.25

Explanation:

As interest is compounded half-yearly.

∴ rate=10/2 = 5% half-yearly

time = 1 year = 2 half-yearly

Compound interest=500xx[(1+5/100)^2-1]

and simple interest=(500xx5xx2)/100

Difference=500xx[(1+5/100)^2-1]-(500 xx5xx2 ) /100

=500xx25/(100xx100)=5/4=₨. 1.25
