Answer 2

Given :

Compound interest on a certain sum for 3 year at 5% be rs 50.44

To find :

What would be the simple interest:

Solution :

First we will find the compound interest on rupees 1

$=(1+5/100)^{3} -1\\= (22/20)^{3}-1\\= 0.331$

So the compound interest on 1 Rs. 0.331

Now for

Simple interest on Rs.1

$=3*5/100\\=3/20\\=0.15$

Now

$3/20 *1/0.331\\= 0.453$

Therefore, the simple interest 0.453 of compound interest is given as

$=0.453*50.44\\=22.85$

Hence, the simple interest would be 22.85
