Question

find rate when principal=rs.500, simple interest rs 150 and time 4 year​

Answer 1

Answer:

let the rate be R

given that, simple intreast,SI=150

principal, P=500

time, T=4year

therefore, SI=P*R*T/100

SI=500*R*4/100

150*100=2000*R

150/20=R

7.5=R

rate=7.5%

Answer 2

Given:

Principal=rs.500, simple interest rs 150 and time 4 year.

We have to find:

Rate..

Formula:

R=(100×Interest)/(Principle ×time)

Solution:

(100×150)/(500×4)

15000/2000

7.5

Answer:

7.5 % is the interest rate.
