Question

what rate percent per annum of simple interest rupees 650 in 3 years​

Answer 1

Step-by-step explanation:

Principal = Rs. 650

Amount = Rs. 741

Time = years and 6 months = 3.5 years

Using the given information we get

interest \: = amount - principal = 741 - 650 = 91interest=amount−principal=741−650=91

Formula of simple interest:

I = \frac{P \times R \times T}{100}I=100P×R×T

where, P is principal, r is rate of interest, t is time in years.

91 = \frac{651 \times r \times 3.5}{100}91=100651×r×3.5

91 = 22.75 \times r91=22.75×r

r \: = 91 \div 22.75r=91÷22.75

r = 4r=4

★Therefore, the rate of interest is 4%.
