Answer:
33.33% gain
Step-by-step explanation:
Let the selling price of 1 pen be Rs. x
Therefore, selling price of 6 pens is Rs. 6x
Since, selling price of 6 pens is equal to cost price of 8 pens
Therefore, cost price of 8 pens = Rs. 6x
Therefore, cost price of 1 pen = Rs. 6x/8
Since, selling price of 1 pen>cost price of 1 pen
Therefore, gain = selling price - cost price
=> x - (6x/8)
=> 2x/8
Therefore, gain%= {(gain/cost price)×100}
=>[{(2x/8)×(8/6x)}×100]
=>[100/3]
=>33.33%
