The table above shows the distribution of the five types of fruit in a fruit stand. If there are 20 more kiwis than oranges, how many fruit are in the fruitstand?

Kiwis and oranges make up 20% and 15% of the total, respectively. Therefore, the difference between the two fruit is 5% of the total.

$$ \begin{array} {|c|c|} \hline \text{Types of fruits} & \text{Percent of fruits} \\ \hline \text{Apples} & 30\% \\ \hline \colorbox{aqua}{\text{Oranges}} & 15 \% \\ \hline \colorbox{aqua}{\text{Kiwis}} & 20\% \\ \hline \text{Bananas} & 20\% \\ \hline \text{Watermelons} & 15\% \\ \hline \end{array} $$

The question mentions that there are 20 more kiwis than oranges. Therefore,

$$ 20 = 5\% \text{ of the total}$$ $$ 20 = 0.05 \cdot \text{total} $$ $$ 20 = \frac{1}{20} \cdot \text{total} $$ $$ 20 \cdot 20 = \text{total} $$ $$ \boxed{400} = \text{total} $$

We can use the answer choices to solve this problem, or just to check our work.

For example, here's how we would go about using the correct answer choice, \( \boxed{400} \).

$$ \text{Kiwis} - \text{Oranges} = 20 $$ $$ 80-60 = 20 \checkmark $$
