@Sayan.
We have studied the formula for Simple interest na.
S.I= (P.R.T) /100 where P=principal, R=Rate, T=Time.
100 is there because rate is specified as a percentage. Just cross multiply the equation P=[(S.I) *100/ (R. T) ] Here P, principal is nothing but the present worth & true Discount is similar to S. I in this case and hence the equation.
