Question

by selling 175 bags a man gains an equal amount to the selling price of 25 bags.find his gain percent

Answer 1

gain=sp-cp
sp of 25 bags=sp of 175bags-cp of 175bags
cp of 175bags=sp of 150 bags

let cp of 1bag be rupee1
cp of 150 bag=rupee150
sp of 150bag=cp of 175bag=rupee175
gain=175-150=25
gain%=25/150×100=50/3%=16 2/3%
