CAT Preparation Community

why is my approach wrong when we can assume only badminton to be 1 and a to be 1 and b to be 1 which nets c to be 13.

why is it still the wrong answer when we can prove it that the total student still equals to 50.

Struggling with today's lrdi daily target (set#187) was not able to understand the video solution also

how should i tackle lrdi for for the remaining days left practice from study room or from mocks and sectionals i have already done pyqs

A survey was conducted to gauge the popularity of three sports magazines viz. - Athlon Sports (AS), Golf Digest (GD) and Runner’s World (RW). A total of 100 candidates participated in the survey. Further, we are given some additional information about their preferences:
1. The number of candidates who liked all three magazines was half of the number of candidates who liked Runner’s World (RW) alone.
2. The number of candidates who liked Athlon Sports (AS) alone is 2 less than the number of candidates who liked both Golf Digest and Runner’s World but not Athlon Sports.
3. The number of candidates who liked both Golf Digest and Runner’s World was thrice the number of candidates who liked all three magazines.
4. A total of 48 candidates liked exactly one magazine. The number of candidates who liked Golf Digest (GD) alone was two more than the number of candidates who liked Runner’s World alone.
5. The number of candidates who liked Runner’s World magazine was more than the number of candidates who liked Golf Digest.
6. The number of candidates who didn’t like any of the three magazines was 2 less than the number of candidates who liked both Golf Digest and Runner’s World.
