Last year, there were 3 sections in the Catalyst, a mock CAT paper. Out of them 33 students cleared the cut-off in Section 1, 34 students cleared the cut-off in Section 2 and 32 cleared the cut-off in Section 3.
10 students cleared the cut-off in Section 1 and Section 2, 9 cleared the cut-off in Section 2 and Section 3, 8 cleared the cut-off in Section 1 and Section 3. The number of people who cleared each section alone was equal and was 21 for each section.1. How many cleared all the three sections?
(a) 3 (b) 6
(c) 5 (d) 7
2. How many cleared only one of the three sections?
(a) 21 (b)63
(c) 42 (d) 52
3. The ratio of the number of students clearing the cut-off in one or more of the
sections to the number of students clearing the cutoff in Section 1 alone is?
(a) 78/21 (b)3
(c) 73/21 (d) None of these
Since, X = 6, the figure becomes:
The answers would be:
1. 6. Option (b) is correct.
2. 21 + 21 + 21= 63. Option (b) is correct.
3. (21+21+21+6 + 4 + 3 + 2)/21 = 78/21. Option (a) is correct.
