In a factory 70% of the workers like oranges and 64% likes apples. If each worker likes, at least one fruit, then what percentage of workers like both the fruit?
Given data:
Percentage of workers like oranges = 70%
Percentage of workers like apples = 64%
Percentage of workers like both oranges and apples = x %
Then,
n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
100 = 70 +64 - n(A ∩B)
n(A∩B) = 34%
Percentage of workers likes both the fruit = 34%.
