Answers With Solution:
S.P. – C.P. = Profit
(150×25+180×20×120% - x×90%×20) – [(150+180+x)×20] = 1230
3750+4320-18x – [(330+x)×20] = 1230
8070-18x – 6600-20x = 1230
-2x = 1230+6600-8070
2x = 240
X = 120 kg.
=750+720+240
=1710
Old profit = 1230
Difference= 1710-1230
=480 Rs.
New profit = 450×20×20%
=1800 Rs.
