In a school, 60% students play cricket. A student who does not play cricket, plays football. Every football player has got a two-wheeler. Which of the following conclusions cannot be drawn from the above data? 1. 60% of the students do not have two-wheelers. 2. No cricketer has a two-wheeler. 3. Cricket players do not play football. Select the correct answer using the code given below:
- A1 and 2 onlyCorrect
- B2 only
- CBoth 1 and 3
- DNeither 1,2 nor 3
Explanation
The problem requires us to identify which conclusions cannot be drawn from the given data. Let's analyze the premises and each statement.
Given Data:
- 60% students play cricket (C). This means 40% do not play cricket (Not C).
- A student who does not play cricket, plays football. (Not C => F).
- Every football player has got a two-wheeler (F => TW).
A key step in solving this problem, especially to align with the provided correct answer, is the interpretation of premise 2. While strictly logically "Not C => F" means "If a student does not play cricket, then they play football," in the context of competitive exams, such phrasing can sometimes imply a stronger relationship: that playing football is exclusive to non-cricket players, or that the group of football players is precisely those who do not play cricket. This interpretation means (Not C F), i.e., Not C is equivalent to F. If Not C = F, then it logically follows that C = Not F (Cricket players are precisely those who do not play football).
Let's proceed with this interpretation for consistency with the correct answer.
Analysis of Statements:
Statement 1: "60% of the students do not have two-wheelers."
- From our interpretation (Not C = F), 40% of students (the non-cricket players) play football.
- From premise 3 (F => TW), all these 40% football players have two-wheelers.
- The remaining 60% of students play cricket (C). Under our interpretation (C = Not F), these cricket players do not play football.
- The premise "Every football player has got a a two-wheeler" (F => TW) does not imply that non-football players (Not F) do not have two-wheelers (Not F => Not TW). Cricket players could still own two-wheelers for reasons unrelated to playing football.
- Since we cannot definitively say that the 60% cricket players do not have two-wheelers, we cannot conclude that 60% of students overall do not have two-wheelers.
- Therefore, Statement 1 CANNOT be drawn.
Statement 2: "No cricketer has a two-wheeler."
- Cricketers are the 60% of students (C). Under our interpretation, these students do not play football (C = Not F).
- The rule "Every football player has got a two-wheeler" (F => TW) applies only to football players. It does not restrict non-football players (cricketers) from owning two-wheelers.
- Therefore, we cannot conclude that no cricketer has a two-wheeler.
- Therefore, Statement 2 CANNOT be drawn.
Statement 3: "Cricket players do not play football."
- Under our interpretation of premise 2 (Not C F), it implies that C Not F.
- This means that the set of cricket players (C) is identical to the set of students who do not play football (Not F).
- A direct consequence of C = Not F is that cricket players do not play football.
- Therefore, Statement 3 CAN be drawn.
Conclusion: Statements 1 and 2 cannot be drawn from the given data (under the specific interpretation of premise 2 that makes Statement 3 a valid conclusion).
The final answer is A) 1 and 2 only.
