Each card in a deck has a positive integer written on one side. Bjorn and Dagmar each draw two cards and divide the number on the first card by the number on the second card to calculate their score. Did Bjorn get a higher score than Dagmar?

(1) If Bjorn had drawn the same two cards in the opposite order, his score would have been lower than Dagmar’s score.

(2) The first card Dagmar drew had a greater number than her second card.

I Plugged in numbers to get the answer.

Asked B>D?
1) 1.1 Let B cards be 5,1 and D cards be 3,1. YES for any positive integer in place of 3!
1.2 Let B cards be 5,1 and D cards be 1,6. NO for any positive integer>5 in place of 6!
Hence, insufficient.

2) Clearly, no data on B. Insufficient.

Combining 1 and 2, It suffices the statement 1.1 and hence sufficient.
C is the answer.

We know for Dagmar, F > S. e.g. the division of the two cards could be 9/3 = 3

For Bjorn, his score in reverse cards could be 2/4 or 2/16 etc
So Bjorn's actual score could be 4/2 = 2 or 16/2 = 4. In one case, it is less than Dagmar's, in the other, it is greater.

So the answer should be (E).

If it is actually (C), please put up a screenshot of the question and solution. Not sure what I am missing.

I got E as well. I can't figure out any way the answer is c.

Each card in a deck has a positive integer written on one side. Bjorn and Dagmar each draw two cards and divide the number on the first card by the number on the second card to calculate their score. Did Bjorn get a higher score than Dagmar?

(1) If Bjorn had drawn the same two cards in the opposite order, his score would have been lower than Dagmar’s score.
Let D's numbers be 3 and 2 so 3/2 =1.5..
B could be 2 and 1 in normal order, then reversed 1/2<1.5 but 2/1 > 1.5 OR B could be 3 and 2 in normal order, then reversed 2/3<1.5 but 3/2= 1.5

Insuff

(2) The first card Dagmar drew had a greater number than her second card.
So D's score is greater than 1
Insuff

Combined..
Let D's numbers be 3 and 2 so 3/2 =1.5..
B could be 2 and 1 in normal order, then reversed 1/2<1.5 but 2/1 > 1.5 OR B could be 3 and 2 in normal order, then reversed 2/3<1.5 but 3/2= 1.5

Insuff

so, answer will be E as pointed by VeritasKarishma

BUT yes, if statement 2 read


(2) The first card Dagmar drew had a greater lesser number than her second card.
This would mean D<1.

Combined
Reverse of B is less than D, that is \(\frac{1}{B}<D<1\)
So, \(\frac{1}{B}<1\) or 1<B (We can X-multiply as B is positive)
so sequence is D<1<B..
answer is YES and sufficient..

Hi can anyone explain the meaning of the statements here.
For 1 statement shouldn't the cards be same for B but in reverse order ie.
D : 4 2
B : 2 4

Kindly correct me if I'm getting it wrong.
