a vendor loses the selling price of 4 oranges on selling 36 oranges . what is his loss percent

10%

Hmmm. Seems to me that he lost 4/36 = 11.1%

If he'd sold 40, and lost 4, that would be 10%

To find the vendor's loss percentage, we need to know the cost price and selling price of the oranges. However, this information is not provided in the question.

If we assume that the cost price and selling price of each orange is the same, we can calculate the loss percentage based on that assumption.

Let's say the cost price and selling price of each orange is x.
Total cost price of 36 oranges = 36x
Total selling price of 36 oranges = 36x - 4x = 32x
Loss = Total cost price - Total selling price = 36x - 32x = 4x

Loss percentage = (Loss / Total cost price) x 100
= (4x / 36x) x 100
= 11.11%

Therefore, if the cost price and selling price of each orange is assumed to be the same, the vendor's loss percentage would be 11.11%.

To find the loss percent, we need to determine the selling price of 4 oranges and compare it to the cost price of those oranges.

Let's calculate the cost price (CP) and selling price (SP) of one orange.

Given:
Number of oranges sold (N) = 36
Loss on selling 36 oranges = Selling price of 4 oranges

Since the loss is equal to the selling price of 4 oranges, we can find the loss on a single orange by dividing the loss by the number of oranges:

Loss on one orange = Loss / Number of oranges = Selling price of 4 oranges / 36

Now, let's calculate the cost price of one orange, which is the selling price plus the loss on that orange:

CP = SP + Loss on one orange

But we know that the vendor loses the selling price on the oranges, so the SP is equal to the CP.

CP = SP = SP + Loss on one orange

Simplifying the equation, we have:

CP = 2 * SP

Now, let's calculate the loss percent:

Loss percent = (Loss / CP) * 100

Substituting the values we have:

Loss percent = ((Selling price of 4 oranges / 36) / (2 * Selling price of 4 oranges)) * 100

Simplifying further, we get:

Loss percent = (1 / (36 * 2)) * 100 = (1 / 72) * 100 = 1.39%

Therefore, the vendor's loss percent is approximately 1.39%.
