Question

ajay bought 100 pencils for rs 250.he was not very good at calculations and made a mistake in fixing his selling price.when he sold his pencils,he incurred a total loss equal to the selling price of 25 pencils.find his loss percent.

Answer 1

Ans: 20%

Cost price of 100 pencil= Rs.250

Let selling price of one pencil=x
Total selling price =100x

Total loss = selling price of 25 pencil=25x
250−100x=25x
125x=250
x=2
Total Loss = 25×2=50


Required loss percent =
$\frac{50 \times 100}{250} = 20\%$


 

Answer 2

Answer:

Step-by-step explanation:

CP of 100 pencil = 250/-

Let SP of 1 pencil = x

Let SP of 100 pencil = 100x

Then, Loss = SP of 25 pencil

SP of 25 pencil = 25x

Simple Loss = CP - SP

= 250-100x = 25x

= 250 = 25x + 100x

= 250 = 125x

= 250/125 = x

= x = 2

Loss = 25 × 2 = 50/-

Loss % = Loss/CP×100

= 50/250×100

= 20%
