A person purchases some article at the rate of rupees 5 per 4 articles and sells them at the rate of rupees 4 per 5 articles. Find the total profit or loss in %.
Answer & explanation
Correct answer: option 4
The correct answer is Option 4: 36 % loss
CP of 4 articles = Rs 5
CP of 20 articles = Rs 25
SP of 5 articles = Rs 4
SP of 20 articles = Rs 16
Since CP > SP, there is a loss.
Loss% = \(\frac{CP_{20}-SP_{20}}{CP_{20}}\) * 100
Loss% = \(\frac{\text{25-16}}{25}\) * 100
Loss% = \(\frac{9 }{25 }\) * 100
Loss% = 36%
