Question

A goods are purchased at rs 450. 1/3rd of it is sold at a loss of 10% ,at what gain % should the remainder be sold so as to gain 20% on the whole transaction

Answer 1

cost of goods=450
1/3rd goods cost =1/3(450)=150
2/3rd goods cost=2/3(450)=300
loss of 1/3rd goods=150*10%=15
profit for further sale of 2/3rd goods=450*20%=90
therefore ,gain% on the further goods sold is= desired profit/cost
=90+15/300
=105/300
=35%
