Q.In a group of persons travelling in a bus, 6 persons can speak Tamil...
Given information:
- 6 persons can speak Tamil
- 15 can speak Hindi
- 6 can speak Gujarati
- None can speak any other language
- 2 persons can speak two languages only
- 1 person can speak all three languages

To find: How many persons are there in the group?

Solution:
Let's assume the number of persons in the group be 'x'.

- Total number of persons who can speak at least one language = 6 + 15 + 6 = 27
- Since 2 persons can speak two languages only, they can be counted as 2 extra language speakers. So, the total number of language speakers = 27 + 2 = 29
- But we have counted the person who can speak all three languages twice (once for each language). So, we need to subtract 2 from the total.
- Hence, the total number of persons in the group = x = 29 - 2 = 27 - 1 = 26

Therefore, there are 26 persons in the group.

Answer: (c) 23.
