Question

What interest rate susan need to secure to make 2500 in interest on 10000 principal over 5years?

Answer 1

interest = 2500
principal = 10000
time = 5 years
then rate = interest * 100/p*t
= 2500*100/10000*5
= 5%
rate of interest = 5%

Answer 2

Answer:

5%

Explanation:

Interest= 2500

Principal= 10000

Time= 5 years

[ we can apply  simple interst or interst formula to find out rate of interst ]

SimpleInterst= Principal*Time*RateofInterest / 100

2500=10000*5*RateofInterest/100

2500=50000*RateofInterest/100            

2500=500*RateofInterest                                  (explanition: 50000/100=500)

RateofInterest= 2500/500            

RateofInterest= 5                                                 (explanition: 2500/500=5)

Rate of Interst is always represented in percentage so the answer is 5%.
