hope my answer is right and help you.

Answer 2

Let the CP of one pen be ₹x.

CP of 15 pens = ₹15x

SP of 12 pens = CP of 15 pens

SP of 12 pens = ₹15x

SP of one pen = ₹15x/12

= ₹5x/4

Profit = SP - CP

= ₹5x /4 - ₹x

= ₹x/4

Profit % = profit / CP * 100

= (₹x/4) / ₹x * 100

= 25%

Ans. = The person had a profit of 25%.
