Question

6. Find the compound interest at 10% p.a. for 2 years on the principal which in 2 years at 10% p.a. yields
200 as simple interest.​

Answer 1

Answer:

Let P be the principle

Simple interest obtained is Rs 200

SI = p×2×10/1000

= 200=p×2×10/1000

= P= RS.1000

A=P (1+r/100)

='1000 (11/10)

= 1000×11×11/10×10

= 1210

CI=A-P =1210-1000

Rs. 210
