Question

A sum of rs. 12,000 amounts to rs. 15,000 in 4 years at the rate of simple interest. Find the rate of interest?

Answer 1

Given,

Principle=rs.12000

Time=4 years

Amount=rs.15000

since, Amount= Principle+Simple interest

so, simple interest = amount - principle

hence, simple interest= rs.15000-12000

S.I.=rs.3000

Now,

By formula,

S.I.=P*R*T/100

3000=12000*R*4/100

3000*100/12000*4=R

R=25/4

R=6.25%

Hope it'll help you!!!

Answer 2

Answer:

6.25

Step-by-step explanation: si= ptr/100

find here R value

then p=12000

         t=4

        si=15000-12000=3000
