Answer 1

Answer:

Step-by-step explanation:

Hello here is your answer

____________________________________

Let rate of interest=r%Time(t)=312

years=7/2 years=3.5

yearsPrincipal amount(P)=Rs 8000

Total amount=Rs 9260

So,  

S.I.=Rs 9260−Rs 8000=Rs 1260

Now,

S.I.=P×r×t100⇒1260=8000×r×3.5100

r=1260×1008000×3.5⇒

r=4.5 %

that's all
