Answer: (d)

11 persons speaks Kannada, n(K) = 11

20 persons speaks Tamil, n(T) = 20

11 persons speaks Telugu, n(Te) = 11

2 persons speaks two languages

n(K ∩ T) +n(T ∩ Te) + (n(K ∩ Te) = 2n

1 persons speaks all the languages, (K ∩ T ∩ Te) = 1

We have

n(K ∪ T ∪ Te) = n(K) + n(T) + n(Te) – [n(K ∩ T)

+ n(T ∩ Te) + n(K ∩ Te)] + n(K ∩ T ∩ Te)

= 11 + 20 + 11 – [ 2 ] + 1

= 42 – 1 = 41

Total persons in the group is 41
