1) LET INITIALLY, THE COMMODITY PRICE=100
AFTER INCREASE BY 20%=120
TO NEUTRALISE THE INCREASE, REQUIRED REDUCTION IN CONSUMPTION=100-100x100/120=100-83.33=16.67%
2) LET BILL AMT=100
DISCOUNT=15
IF DISCOUNT IS 15, THEN BILL=100
IF DISCOUNT IS 540, THEN BILL=100x540/15=3600
3) LET COST PRICE=100
AFTER MARKING BY TRADER=112
DISCOUNT=112x5/100=5.60
SALE PRICE=112-5.60=106.40
PROFIT %= 6.4%
