Question

* 2. Find the rate, if sI = 150, principal (P)
= * 1000 and time (T) = 2 yr.​

Answer 1

Answer:

Rate of Interest =7.5%

Step-by-step explanation:

Principal Amount =Rs 1000

Time=2 years

Simple Interest =Rs 150

Let Rate of Interest be x

SI=PRT/100

150=P×R×T/100

150=1000×x×2/100

150×100=1000×x×2

15000=1000×x×2

15000÷1000=x×2

15=x×2

15÷2=x

7.5=x

Rate of Interest =7.5%
