If principal = P, Rate R = R% per annum, T = Time year, SI = Simple interest, then 

A. $T=\frac{100×SI}{P×R}$

B. $SI=\frac{P×R×T}{100}$

C. $R=\frac{P×SI×T}{100}$

D. $T=\frac{P×SI×R}{100}$

E. $R=\frac{100×SI}{P×T}$

A, B and E only

Actual formula of S.I. = $\frac{P×R×T}{100}$

Therefore,

A. T= $\frac{100×SI}{P×R}$

B. SI= $\frac{P×R×T}{100}$

E. R= $\frac{100×SI}{P×T}$

These options are correct.
