Question -
Answer -
We have,
People who like oranges = 76%
People who like bananas = 62%
Let people who like oranges be n (O)
Let people who like bananas be n (B)
Total number of people who like oranges or bananas = n (O ∪ B) = 100
People who like both oranges and bananas = n (O ∩ B)
We know,
n (O ∪ B) = n (O) + n (B) – n (O ∩ B)
Substituting the values we get
100 = 76 + 62 – n (O ∩ B)
100 = 138 – n (O ∩ B)
n (O ∩ B) = 38
∴ People who like both oranges and banana is 38%.
