Answers With Solution:
1. Ans. D.
Solution:
C.P. of rice = 25/125×100
=20 Rs. per kg.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.
2. Ans. B.
Solution:
The rice that is sold at a loss of 10% is 120 kg.
150+180+120 = 450 kg.
3. Ans. C.
Solution:
Profit = 150×20×25%+180×20×20%+120×20×10%
=750+720+240
=1710
Old profit = 1230
Difference= 1710-1230
=480 Rs.
=750+720+240
=1710
Old profit = 1230
Difference= 1710-1230
=480 Rs.
4. Ans. A.
Solution:
Total rice = 120+150+180
=450 kg.
New profit = 450×20×20%
=1800 Rs.
New profit = 450×20×20%
=1800 Rs.
