Q 9.

If there is a 60% increase in an amount in 6 years at simple interest then, what will be the compound interest of Rs. 12000 after 3 years at the same rate of interest p.a. compounded annually?

Options:

3972

4280

5780

6240

1st part:

Let principal P = 100

Rate = R% p.a.

Time T = 6

As there is a 60% increase

so, I = 60% of P = 60

Therefore, R = (I x 100) / (PT)

or, R = (60 x 100) / (100 x 6)

= 10% p.a.

Now, calculate the compound interest.

Q 10.
