Question

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

Answer 1

hey,

SP = 17

cp = 16

gain = 17 - 16

gain = 1

gain% = 1 * 100/16

gain% = 6.25℅

Answer 2

Let C.P of 1 bottle be x
hence
C.P of 17 bottles = 16x
S.P of 17 bottles = 17x
Now,
Profit=S.P-C.P
= 17x-16x
= x
p%=(x\16x)×100
= 6.25%
