A survey shows that `73%` of the Indians like apples, whereas `65%` like oranges. What percentage of Indians like both apples and oranges ? |

Answer» Let A = Set of Indians who like apples. And B = Set of Indians who like oranges. Then, `n(A) =73, n(B) =65 and n(AcupB) = 100`. `n(A cap B) =n(A) +n(B)-n(A cupB ) =(73+65-100) =38`. |
