Question

How long will Rs1500 to yield a S.I of Rs30 at rate 8% per annum? ​

Answer 1

I = PTR/100

Solving for R we get,

R=(I*100)/(P*T)

R= (30*100)/(1500*4) = 3000/6000 = 0.5%

Let us verify for second instance

I = 1500*8*0.5/100 = 6000/100 = 60

There Rate of Interest is 0.5%

Answer 2

Answer:

2/3 years

Step-by-step explanation:

simple interest = P*R*T/100

80 = 1500*8*T/100

80 * 100/1500*8 = T

10/15 = T

2/3 = T

T = 2/3 years
