Question

the cost price of 12 fans is equal to the selling price of 16 fans.Find the gain or loss percent

Answer 1

Let the cost price of 12 fans be a

Selling price of 16 fans = a

Cost price of one fan = a / 12

Selling price of one fan = a/16

Loss on one fan = CP - SP

= a/12 - a/16

= ( 4a - 3a) /48

= a / 48

Loss percent = Loss × 100 / CP

= ( a /48) × 100 / (a / 12)

= 100 /4

= 25 %

Answer 2

Answer:

Loss=25%

Step-by-step explanation:

Let the cost price of 12 fans be x

Selling price of 16 fans = x

Cost price of one fan = x / 12

Selling price of one fan = x/16

Loss on one fan = CP - SP

= x/12 - x/16

= ( 4x - 3x)/48

= x/48

Loss percent Loss x 100 / CP

= (x/48) 100 / (x/12)

= 100 /4

= 25%
