Question

If the selling price of 16 water bottles is equal to the cost price of 17 water bottles, find the
gain per cent earned by the dealer.​

Answer 1

SP of 16 bottle= CP of 17 bottle or

16 SP = 17 CP

SP/ CP = 17/16

we can assume SP=17 , CP= 16

So profit % = {(17-16)/16}×100 = (1/16)×100

= 6.25%
