The simple interest on a sum of money at 12% per annual for 8 years is half of the sum. The sum is______.

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

a. $T = \frac{100 \times SI}{P \times R}$

b. $SI = \frac{P \times R \times T}{100}$

c. $R = \frac{P \times SI \times T}{100}$

d. $T = \frac{P \times SI \times T}{100}$

e. $R = \frac{100 \times SI}{P \times T}$
