Question

Suresh borrowed ₹ 6000 from his friend and returned ₹ 7500 after 2 years.The rate of interest is?

Answer 1

Principal = ₹6000

Time = 2 years

Amount = ₹7500

S.I = ₹7500- ₹6000 = ₹1500

Rate of interest =?

We find this using two formula

1st = R = s.i×100 / P×T

2nd S.I = P×T×T/100

We use 1st formula = S.I×100/P×T

1500×100/6000×2

150000/12000

12.5 %

2nd formula = S.I = P×R×T/100

1500 = 6000× R× 2/100

1500×100 = 12000× R

R = 150000/12000

R = 12.5%

You can use any formula
