Answer 1

According to the question,

Selling price of 50 pens = Cost price of 80 pens

To find : The profit or loss percent.

Let the cost price of 1 pen be ₹1

Hence,

Cost price of 80 pens = ₹80

Selling price of 50 pens = ₹80 (as the cost price of 80 pens is equal to the selling price of 50 pens)

Cost price of 50 pens = ₹50 (since we have taken 1 pen to be ₹1)

Clearly, there's a profit.

Profit = Selling price - Cost price

Profit = ₹80 - ₹50

Profit = ₹30

Profit% =

(profit/cost price) × 100

30/50 × 100

by reducing to the lowest terms we get,

Profit% = 60%

Therefore option (d) 60% profit is correct.

Hope it helps!

have a great day!

Profit % = profit / cp * 100
= 30/50 *100
= 60 %
