If M is the marked price then the selling price is
(1-A/100)(1-B/100)×M.
Thus if M=100,
SP=(1-A/100)(1-B/100)×100.
Hence, Discount=(M-SP)=100-SP
=> D(%)= (M-SP)/M ×100= 100-SP.

Let suppose be the price of material to be100
For A%discount=100-100*A%
=100-A
for AGAIN B%discount=(100-A)-(100-A)*B%
=100-A-B+(AB)/100
Net discount=(INITIAL COST-FINAL
COST)*100/INITIAL COST
= (100-100+A+B-(AB)/100)*100/100
Finally=A+B-(AB/100)
