Question

praveen borrowed ₹6000 from his friend and returned ₹7500 to him after two years,calculate the rate of interest​

Answer 1

Step-by-step explanation:

p = 6000₹

si = 7500 - 6000

= 1500

t = 2yrs

si = ptr/100

1500 = (6000 × r × 2)/100

(1500 × 100 )/12000 = r

r = 12.5%

Answer 2

Answer:

Simple interest = 12.5%

I don't know which interest are you talking about, you haven't mentioned the rate of ? interest so I think you are talking about simple interest.

Step-by-step explanation:

Here is the formula=$\frac{p \times r \times t}{100} = 7500$

where p is the principle

r is the rate

t is the time

I hope you got your answer.

If it was compound interest

Here is the formula=

$p \times ( 1 + { \frac{r}{100}) }^{t} = 7500$

where p is the principle

r is the rate

t is the time.
