Question

Find the compound interest at the rate of 10% per annum for two years on that principal which in two years at the rate of 10% per annum given Rs. 200 as simple interest.

Answer 1

Answer:

Compound Interest = A – P = Rs 1210 – Rs 1000 = Rs 210

Step-by-step explanation:

Solution⤵️

Given details are

Simple interest (SI) = Rs 200

Rate (r) = 10 %

Time = 2 years

So, by using the formula,

Simple interest = P×T×R/100

P = (SI × 100)/ T×R

= (200 × 100) / 2 × 10

= 20000/20

= Rs 1000

Now,

Rate of compound interest = 10%

Time = 2years

By using the formula,

A = P (1 + R/100) n

= 1000 (1 + 10/100)2

= 1000 (110/100)2

= Rs 1210

∴ Compound Interest = A – P = Rs 1210 – Rs 1000 = Rs 210
