Question

At what rate per cent per annum simple interest will 66000 amount to 72720 in 2 year

Answer 1

Answer:

Principal,P = Rs. 66,000

Time,T = 2 years

S.I. = 72,720 - 66,000 = Rs. 6,720

Rate,R = ?

\therefore∴ S.I. = \dfrac{P\times R\times T}{100}  

100

P×R×T

\Rightarrow⇒ R =  \dfrac{6720 \times 100}{66,000 \times 2}  

66,000×2

6720×100  

\Rightarrow⇒ Rate = 5.095.09% per annum
