There are 800 0ranges in a box. If 15% of oranges are rotten, find the number of rotten oranges.

Given, Percentage of rotten oranges= 15%

Total number of oranges in a box = 800

$\therefore$Number of rotten oranges = 15% of 800

$\Rightarrow$ $\frac{15}{100}\times 800$

$\Rightarrow$ 120 oranges are rotten.
