Answer 1

Answer:

Step-by-step explanation:

Given that, Selling price of 10 pens = cost price of 14 pens

So, let the cost price of 1 pen be Rs x

Selling price of 10 pens = Rs x

Selling price of 1 pen =Rs x/10

By using the formula,

Gain = selling price – cost price

= 14x/10 – x

= 4x/10

By using the formula,

Gain % = (gain/cost price) × 100

= (4x/10)/x × 100

= 2/5 × 100

= 4
