Question

100 pens are purchased at the rate of Rs.500 and 12 pens are sold for Rs.48.
What is the profit or loss percentage?​

Answer 1

Answer:

it is loss

if 100 pens are purchased at the rate of Rs.500 ,

cost of 1 pen = 5

then cost of 12 pens = 60

therefore loss = 60 - 48 = 12

Step-by-step explanation:

loss percentage = loss × 100/CP

= 12 ×100/60

= 20%

Answer 2

Answer:

Loss percentage  = 20%

Step-by-step explanation:

Given,

100 pens purchased for Rs. 500

12 pens sold for Rs. 48

To find,

Profit or loss percentage

Recall the Concepts,

If the Selling price is greater than the Cost price, then there is profit

If the Cost Price is greater than the Selling price, then there is loss.

Loss = CP - SP ----------------(A)

Loss percentage = $\frac{Loss}{CP} X100$ ---------------(B)

Solution:

CP of 100 pens = 500

CP of 1 pen = $\frac{500}{100}$ = 5

SP of 12 pens = 48

SP of 1 pen = $\frac{48}{12}$ = 4

Since, CP > SP, then it is loss

Loss = CP - SP  = 5 - 4 = 1.

From formula (B),

Loss percentage = $\frac{Loss}{CP} X100$

= $\frac{1}{5} X100$

=20%

∴Loss percentage  = 20%
