Question

If the selling price of 16 bottles is equal to the cost price of 17 bottles find the gain percent earned by the dealer

Answer 1

let SP of 1 Bottle be x

SP of 16 bottles = ₹16x
CP of 17 bottles = ₹16x
CP of 1 bottle =16x/17

as
SP is greater than CP=Profit
PROFIT= x-16x/17=x/17
P%=x/17÷16x/17×100
P%=6.25%

hope it helps
