I brought six pencil at 5000 each but sold them at 3000 each. What was my percentage loss?

To calculate the percentage loss, you need to find the difference between the cost price and the selling price, then divide it by the cost price and multiply by 100.

Cost price of each pencil: $5000
Selling price of each pencil: $3000

Loss per pencil = Cost price - Selling price = $5000 - $3000 = $2000

Percentage loss = (Loss / Cost price) * 100

= ($2000 / $5000) * 100

= 40%

Therefore, your percentage loss is 40%.

To calculate the percentage loss, we need to find the difference between the selling price and the cost price, and then divide it by the cost price.

Cost Price of 6 pencils = 6 * 5000 = 30000
Selling Price of 6 pencils = 6 * 3000 = 18000

Loss = Cost Price - Selling Price = 30000 - 18000 = 12000

Percentage Loss = (Loss / Cost Price) * 100
Percentage Loss = (12000 / 30000) * 100
Percentage Loss = 40%

Therefore, the percentage loss is 40%.
