t answerBy selling 168 Pens a shopkeeper gains the of CP of 14 pen. Find his Gain %?

Sure, here is the step by step solution:

Step 1: Understand the problem The shopkeeper sells 168 pens and the profit he makes is equal to the cost price of 14 pens. We need to find the profit percentage.

Step 2: Calculate the profit per pen If the shopkeeper's profit from selling 168 pens is the cost price of 14 pens, then the profit per pen is the cost price of 14 pens divided by 168 pens.

Profit per pen = Cost Price of 14 pens / 168 pens

Step 3: Calculate the cost price per pen The cost price per pen is the total cost (which is the same as the selling price since the profit is included in the selling price) minus the profit per pen.

Cost Price per pen = Selling Price per pen - Profit per pen

Step 4: Calculate the profit percentage The profit percentage is the profit per pen divided by the cost price per pen, multiplied by 100.

Profit % = (Profit per pen / Cost Price per pen) * 100

By substituting the values from step 2 and step 3 into step 4, we can find the profit percentage.
