A survey shows that 63 % of the people in a city read newspaper A whereas 76 % read news paper B . If x % of the people read both the newspapers, then a possible value of x can be:

Step-by-step solution

n A = 63 n B = 76 n A ∩ B = x Let n ∪ = 100 n A ∪ B = n A + n B − n A ∩ B ≤ 100 ⇒ 63 + 76 − x ≤ 100 ⇒ x ≥ 39 But n A ∩ B ≤ n A ∴   39 ≤ x ≤ 63 .
