Question

Sweet corns purchased for $9 are markup by 10%. When no one bought the sweet corns, they decided to markdown the corn by 10% from the markup price. What is the selling price of the corn?
$8.91
$8
$9.10
$8.60

Answer 1

To determine the selling price of the sweet corn after the markup and markdown, we can follow these steps:

1. **Calculate the markup price:**
The original purchase price of the sweet corn is $9.
The markup is 10% of the purchase price.

\[
\text{Markup} = 10\% \times 9 = 0.10 \times 9 = 0.90
\]

Now, add the markup to the original price to find the markup price:

\[
\text{Markup price} = \text{Original price} + \text{Markup} = 9 + 0.90 = 9.90
\]

2. **Calculate the markdown price:**
The markdown is also 10%, but this time it is 10% of the markup price.

\[
\text{Markdown} = 10\% \times 9.90 = 0.10 \times 9.90 = 0.99
\]

Now, subtract the markdown from the markup price to get the selling price:

\[
\text{Selling price} = \text{Markup price} - \text{Markdown} = 9.90 - 0.99 = 8.91
\]

Thus, the selling price of the corn is **$8.91.**
