Question

6. or loss per cent. Hint. Suppose he buys (12 x 5) = 60 lemons. 7. The selling price of 12 pens is equal to the cost price of 15 pens. Find the gain per cent. Find the loss per cent.​

Answer 1

Answer:

Let the cost price of 1 pen =Rs.1

So, cost price of 12 pens =Rs.12

SP of 15 pens =Rs.15

From the question,

Selling price of 12 pens = cost price of 15 pens

Gain =SP−CP

= 15 − 12

= Rs.3.

Gain % = {(gain/CP)×100}

= {(3/12)×100}

= {300/12}

= 25%.
