Options- A. 40

- Correct Answer
- 42
ExplanationAccording to question ,
Let us assume Number of Kannada = K , Number of Tamil = T and Number of Telugu = Te
Here , n(K) = 11; n(T) = 20; n(Te) = 11
n(K ? T ? Te) = 1
n(K ? T) = n(T ? Te) = n(Te ? K) = 2
n(K U T U Te) = n(T) + n(K) + n(Te) - n(K ? T) - n(T ? Te) - n(Te ? K) + n(K ? T ? Te)
n(K U T U Te) = 20 + 11 + 11 - 2 - 2 - 2 + 1 = 37 - 1. Who sits second to the left of V?
