Question

At a certain rate of simple interest rs 3200 becomes rs 4000 in 2 years. What sum of money will become rs 7754 in 3 years at same rate of interest

Answer 1

Answer: 10080.2 rs

Step-by-step explanation:

3200/4000 = 0.8. Subtract 1 from 0.8 to find percent of interest.

Then divide into 2 because the question says that it's in a span of 2 years.

20%/2 = 10%

Now that you have your interest rate, apply it to your 7754 rs in 3 years.

1.1 x 7754 = 8529.4

Subtract 8529.4 with 7754 to find interest in a year.

8529.4 - 7754 = 775.4

Multiply by three and and add back to 7754.

775.4(3) + 7754 = 10080.2
