Question

A man sold 3/5 of the goods at 20% loss.At what profit % should he sell the remaining goods to get 10% profit on the whole

Answer 1

let 100 be total goods
3/5(100)=60;2/5 (100)=40
loss of 60 goods is 12
desired profit is 10% on overall=100*10%=10
therefore total desired profit is 22 for new selling of 40 goods
henceprofit% to sell=(desired profit/cost)*100
profit% to sell = (22/40)*100=55%
