Question

Robert bought 99 oranges from a shop. 22 of the oranges turned out rotten. What percentage of the oranges are not rotten?

• A. 77.78%
• B. 77.84%
• C. 77.62%
• D. 77.56%

Answer 1

The correct option is A 77.78%

Number of oranges bought by Robert = 99
Number of oranges found rotten = 22

Number of oranges that are not rotten = 99 - 22 = 77

Fraction of oranges that are not rotten =$\frac{77}{99}\times 100$ = 77.78%

Hence, 77.78% of the oranges are not rotten.
