How comes this formula T.D. = B.D. x 100 / 100+(R*T)
Atually T.D = Amout*rate*time / 100+(R*T)
--------------------------------------------------------------------------------
B.D = amount*rate*time/100
T.D = (amount*rate*time/100)*100/100+(rate*time)
= amount*rate*time/100+(rate*time)
Atually T.D = Amout*rate*time / 100+(R*T)
--------------------------------------------------------------------------------
B.D = amount*rate*time/100
T.D = (amount*rate*time/100)*100/100+(rate*time)
= amount*rate*time/100+(rate*time)

How to come B.D.=(A*R*T)/100;
T.D.=(A*R*T)/[100+(R*T)];
THEN T.D.=[(A*R*T)*(100/100)]/[100+(R*T)];
T.D.=[((A*R*T)/(100))*100]/[100+(R*T)];
T.D.=BD.*100/[100+(R+T)]
T.D.=(A*R*T)/[100+(R*T)];
THEN T.D.=[(A*R*T)*(100/100)]/[100+(R*T)];
T.D.=[((A*R*T)/(100))*100]/[100+(R*T)];
T.D.=BD.*100/[100+(R+T)]

short cut:
p*r*t
420*15%*4/12 = 20
420-20 = 400
p*r*t
420*15%*4/12 = 20
420-20 = 400
