Question

86. The simple interest on Rs. 6000 at certain rate
of interest for 7 years is Rs. 3780. What is the
rate of interest per annum?

​

Answer 1

Answer:

Simple interest per annum is 9%

Step-by-step explanation:

simple interest =(P*R*T)/100

Given that

SI=simple interest =3780

P=principle=Rs 6000

T=time =7years

R =Rate =?

Now

(6000*R*7)/100=3780

420*R=3780

R=3780/420=9

The rate is 9%
