Answer 1

Answer:(2) 10 %

Step-by-step explanation:

●The intrest in 6 months is 32.50 rupees.

●So the intrest in 1 year/12 months will be 65 rupees

● since we need to find the rate of intrest of 1 year we can apply the formula of

I= (P×R×T)/100.

● Ultimately be putting the values of

I=65

P=650

R=?

T=1 year

We will get 10%

Answer 2

Answer:

10

Step-by-step explanation:

SI = P*T*R/100

P =650

T(in years) = 0.5

SI = 32.50

R = SI*100 / P*T

= (32.50*100) / (650 *0.5)

= 10

:R = 10
