Question

 a student buys 3 pencils each for Rs.4 and sells all at 4 for Rs. 5. His gain or loss per cent is

Answer 1

loss is 0.08 ( cp of 1 pencil 1.33 sp of one pencil 1.25) and loss percent 0.08 / 1.33 ×100 = 24.24 %

Answer 2

Answer:

The loss percentage for 1 pencil for the student = 68.75%

Step-by-step explanation:

Student buys each of the 3 pencils for Rs. 4

⇒ C.P. for 1 pencil = Rs. 4

Student sells 4 pencils for Rs 5

$\implies \text{S.P. for one pencil = }\frac{5}{4}=1.25$

So, as C.P > S.P

So, student will be in loss and the corresponding loss percentage is :

$\text{Loss Percentage = }\frac{C.P. - S.P.}{C.P.}\times 100\\\\\implies \text{Loss Percentage = }\frac{4-1.25}{4}\times 100\\\\\bf\implies \textbf{Loss Percentage = }68.75\%$

Hence, The loss percentage for 1 pencil for the student = 68.75%
