In a school, all the students play at least one of three indoor games ...
⇒ 50 + 28 + x + 12 − x + 21 + x
⇒ 111 + x (total)
The maximum value for x=12 111 + x = 0
111 + 12 = 0
The maximum value = 123
⇒ 111 + x (total)
The maximum value for x=12 111 + x = 0
111 + 12 = 0
The maximum value = 123

In a school, all the students play at least one of three indoor games ...
Maximum number of students in the school:
- Given Data:
- 60 play chess
- 50 play table tennis
- 48 play carrom
- 12 play chess and carrom
- 15 play carrom and table tennis
- 20 play table tennis and chess
- Approach:
- Let's start by finding the total number of students who play each game individually.
- Then, we will consider the students who play two games simultaneously and subtract them to avoid double counting.
- Finally, we will add all the students to find the maximum number of students in the school.
- Calculations:
- Number of students playing only chess = 60 - 12 - 20 = 28
- Number of students playing only table tennis = 50 - 20 - 15 = 15
- Number of students playing only carrom = 48 - 12 - 15 = 21
- Number of students playing chess and table tennis = 20
- Number of students playing all three games = 12 (as given)
- Total number of students:
- Total = Students playing chess + Students playing table tennis + Students playing carrom - Students playing two games simultaneously + Students playing all three games
- Total = 28 + 15 + 21 - 20 + 12 = 56
- Conclusion:
- Therefore, the maximum number of students in the school can be 56.
Hence, the correct answer is option B) 123.
