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

Step-by-step explanation:

sp of 16bottles = cp of 17bottles

16×sp= 17×cp

16sp= 17cp

sp/cp= 17/16

hence ratio of sp and cp is 17:16

cp= 16x

sp= 17x

sp>cp. it means gain

Gain= sp-cp

= 17x-16x

= x

gain% = (gain/cp)×100

gain% = (x/16x)×100

gain%= 100/16

gain%= 6¼%
