Question

if the sp of 16 water bottles is equal to the cp of 17 water, find the gain % earned by the dealer

Answer 1

let the cp of each bottle be x
then cp of 16 water bottles= 16x
cp of 17 bottles= 17x
sp of 16 bottles=cp of 17 bottles= 17x
thus, cp=16x and sp=17x
since sp is greater than cp then it is a gain of 1x
gain percent= gain/cp x 100
= [1x/16x] x 100=  6 1/4 % [mixed fraction]
