Answer 2

Given:

Rs.2000 gives an interest rate of rs. 1200 at 7% p.a.​

To find:

The time

Solution:

The sum of money, P = Rs. 2000

The simple interest, S.I. = Rs. 1200

The rate of interest, R = 7% p.a.

Let "T" represents the no. of years.

We know,

$\boxed{\bold{Simple \:Interest = \frac{P\times R\times T}{100} }}$

Therefore, we get

$1200 = \frac{2000 \times 7 \times T}{100}$

$\implies 1200 = 20 \times 7 \times T$

$\implies 60 = 7 \times T$

$\implies T = \frac{60}{7}$

$\implies \bold{T = 8.5 \:years}$

Thus, in 8.5 years Rs. 2000 will give an interest rate of Rs. 1200 at 7% p.a.
