Question

The compound interest on a sum of money for two years is ₹1331.20 and the simple interest​

Answer 1

Answer:

It is given that

CI for 2 years = 1331.20

SI for 2 years = 1280

So the difference = 1331.20 - 1280 = 51.20

Here 51.20 is the simple interest on 1280/2 = 640 for one year

We know that

Rate = (SI×100)/(P×t)

Substituting the values

=(51.20×100)/(640×1)

Multiplying and dividing by 100

=(5120×100)/(100×640)

= 8% p.a.

So the SI for two more years at the rate of 8% p.a.

Sum =(SI×100)/(r×t)

Substituting the values

=(1280×100)/(8×2)

= 8000
