Out of 800 oranges, 50 are found rotten. Find the percentage of good oranges.

Given:

Total number of oranges = 800

Number of rotten oranges = 50

Number of good oranges = 800 - 50 = 750

Percentages of good oranges = $\dfrac{\text{Number of good oranges}}{\text{Total number of oranges}} \times 100$ %

= $\dfrac{750}{800} \times 100$ %

= $\dfrac{75,000}{800}$ %

= $\dfrac{375}{4}$ %

= $93\dfrac{3}{4}$ %

The percentage of good oranges = $93\dfrac{3}{4}$ %
