Question

the simple interest earned on a certain amount is double the amount when invested for 10 years​

Answer 1

Answer:

Refer the example below:

Rate of Interest being offered is 20 %.

Explanation:

When invested amount is getting double after 10 years then rate of interest would be 20%.

Let us say for example

X is investing 100 rs for 10 years at the rate of 20 %.

Then, solution would be as below.

A =\frac{PNR}{100}

100

PNR

A = 100 \times 10 \times 0.20100×10×0.20

A = Rs. 200

If X is investing Rs. 200 rs for 10 years at the rate of 20 % then A would be Rs. 400.
