Question 18
HardOriginal questionStatement: At the Sunrise Coaching Centre, every student who scores above 80 in the weekly test gets a reward card. This week Tanvi got a reward card, and Farhan scored 85 in the test.
Conclusions:
I. Farhan got a reward card this week.
II. Tanvi scored above 80 in this week's test.
Which conclusions follow?
Show the answer and explanation
Correct answer: A
Explanation
I follows: Farhan scored 85, which is above 80, and every such student gets a reward card.
II does not follow: the rule says a score above 80 brings a card, not that a card comes only from a score above 80. Tanvi may have got hers for some other reason, such as full attendance.
So only I follows.
Worth noting
"Every A gets B" does not mean "everyone with B had A". Running a rule backwards is the classic trap in this chapter.
