i think (1) should be correct because n(AUB) = 200 , n(A) = 120 , n(B) = 144 , n( A intersection B ) = x n(AUB) = n(A) + n(B) - n(A intersection B) x = 120 + 144 -200 x = 64 n = 120 because maximum no. of population like tea is 120 m = 64 as calculated above so n-m => 120 -64 => 56 hence (1) is correct
