Question

The compound interest of a certain sum for 2 years is Rs8034 and the simple interest of the same sum for the same interval of time at the same rate of interest is 7800. Find the sum and rate of interest.​

Answer 1

Answer:

Rs 65,000

Step-by-step explanation:

Simple interest for 2 years = Rs 7800

So for 1 year = Rs 3900

Compound interest and simple interest are same for the first year

So compound interest for second year = 8034 - 3900

                                                                 =  Rs 4134

So interest on Rs 3900 is 4134 – 3900 = 234

So rate = 234/3900 x 100 = 6% ANSWER

6% =3900

100% = 100/6 x 3900

         = Rs 65,000

                     I hope this answer will help you.................
