16% of apple in a basket go bad. If there are 42 good apples in the basket, find the total number of apples in the basket?
Denote the total number of apples as X. If 16% are bad, good apples are 100%-16% = 84% or 0.84X apples.
Given that
0.84X = 42
thus
X = 42/0.84 = 50 apples.
Answer: there are 50 apples in the backet.
