Question

the cost price of 8 fan is equal to the selling prices of 6 fan . find he gain percent​

Answer 1

Let the CP of one fan be ₹100

So the cost of 8 fans = ₹100×8

=₹800

It is given that the SP of 6 fans = CP of 8 fans

SP of 1 fan = CP/The number of fans sold

= 800/6

= ₹400/3

GAIN = 400/3 - 100

= 400/3 - (100/1 × 3/3)

= 400 - 300/3

= ₹100/3

Gain percent = Gain/CP ×100

= (100/3)/100 × 100

= 100/3

$= 33 \frac{1}{3} \%$
