(6-10)Consider the following table that presents the results of a competitive MCQ examination, where candidates were tested in their knowledge of physics, chemistry, mathematics and computer science. The table contains the data on the number of candidates securing marks within the specified range of marks. For example, [81-100] specifies the range of marks as ≥81 and ≤100. Marks-wise distribution of candidates:
| Subject | Total Marks | [81-100] | [71-80] | [61-70] | [51-60] |
| Physics | 100 | 0 | 1 | 4 | 85 |
| Chemistry | 100 | 2 | 5 | 875 | 3350 |
| Maths | 100 | 0 | 0 | 0 | 6 |
| Computer science | 50 | 0 | 0 | 0 | 0 |
| Subject | [41-50] | [31-40] | [21-30] | [11-20] | [0-10] |
| Physics | 730 | 4205 | 10885 | 9170 | 1920 |
| Chemistry | 6775 | 7778 | 5065 | 1800 | 1350 |
| Maths | 199 | 3400 | 15045 | 6975 | 1375 |
| Computer science | 220 | 2145 | 10140 | 11858 | 2637 |
6. What is the ratio of the total number of candidates who scored more than 50 marks in physics to those who scored more than 40 marks in mathematics?
1. 17:49

7. If securing over 40% marks is the qualifying criteria for each subject, then the ratio of the number of candidates who qualify in Mathematics compared to those who qualify in computer science is:
1. 15:42
2. 1:2
3. 56:1
4. 1:61
यदि प्रत्येक विषय के लिए योग्यता मानदंड 40% से अधिक अंक प्राप्त करना है, तो कंप्यूटर में उत्तीर्ण उम्मीदवारों की तुलना में गणित में उत्तीर्ण उम्मीदवारों की संख्या का अनुपात विज्ञान है:
SHOW ANSWER
AnswerExplanation: Math: 199 + 6
Comp sci.=40% of 50 = 20 marks= 10140 + 2145+220
= 205:12505

10. If securing over 60% marks is the qualifying criteria for each of the three subjects of Physics, Chemistry and Mathematics, then the number of candidates who have qualified in all three subjects is:
1. 0
2. 90
3. 6
4. 5
यदि 60% से अधिक अंक हासिल करना भौतिकी, रसायन विज्ञान और गणित के तीनों विषयों में से प्रत्येक के लिए योग्यता मानदंड है, तो तीनों विषयों में उत्तीर्ण होने वाले उम्मीदवारों की संख्या है:
SHOW ANSWER
Answer 1Explanation: In maths 0 Qualify over 60%
So no one qualified in all three subjects.
