Answer 1

Jane is borrowing money from her sister , who is charging her simple interest using the formula I = Prt , where P is principal, r is rate of interest and t is the time taken .

we have to find r in term of I , P and t

Given, I = Prt

r = I/Pt

so, answer should be r = I/Pt .

I think your write first option I/Pt , then correct choice should be (A).

Answer 2

I=Prt
rt= I/P
r=I/pt

Hence , option a.is right
