Question

3. At what rate of interest will Rs 300 yields Rs. 45 as simple interest in 3
years?​

Answer 1

Answer:

Simple interest = P×R×T/100

45 = 300×R×3/100

Cross multiply

45×100 = 900R

Divide both sides by 900

4500/900 =900R/900

5 = R

R =5%

Therefore the rate at which Rs. 300 yield Rs. 45 simple interest in 3years is 5% .
