Classification of 50 Students based on the marks obtained by them in Quants & Reasoning in Prelim exam
| Subject | Mark Out of 100 | ||||
|---|---|---|---|---|---|
| 80 and above | 70 and above | 50 and above | 30 and above | 0 and above | |
| Quants | 23 | 28 | 37 | 43 | 50 |
| Reasoning | 12 | 32 | 35 | 39 | 50 |

Q1
The number of students scoring less than 30% marks in aggregate is?
- A. 15
B. 5
C. 20
D. 10
We have 30% of 100 = [latex] (\frac {30}{100}) \times 100 = 30[/latex]
Therefore Required number
= Number of students scoring less than 30 marks in aggregate
= 50 – Number of students scoring 30 and above marks in aggregate
= 50 – 40 = 10.
Q2
If it is known that at least 20 students were eligible for main exam, then the minimum qualifying marks in Reasoning for eligibility to attend the main exam(Top 20 students only can attend main exam )?
- A. 70-80
B. above 80
C. 70-60
D. 50-70
12 students secured above 80 then remaining 8 student will scored in the range 70-80
Q3
The percentage of number of students scored 70% marks in Quantitative is what percentage of number of students scored 30% marks in aggregate ?
- A. 60%
B. 70%
C. 50%
D. 75%
Number of students scored 70% marks or 70 in Quantitative = 28
Number of students scored 30% marks or 30 in aggregate = 40
% = [latex] \frac {28}{40} \times 100 = 70[/latex] %
Q4
If at least 50% marks in aggregate are required for interview, how many students will be eligible to attend interview?
- A. 50
B. 40
C. 20
D. 38
50% of 100 = [latex] \frac {50 \times 100} {100} = 50[/latex]
No of students scored 50 aggregate = 38
Q5
What is the different between the number of students passed with 80 as cut-off in Quants and 30 as cut-off in aggregate together to no of students passed with 70 as cut-off in aggregate and 50 as cut off in Reasoning?
- A. 11
B. 5
C. 8
D. 6
Difference = (23 + 40 ) – ( 22 + 35) = 6
