Comprehension

In a Class X Board examination, ten papers are distributed over five Groups: PCB, Mathematics, Social Science, Vernacular, and English. Each paper is evaluated out of \(100\).

The final score of a student is calculated as follows:

  1. First, the Group Scores are obtained by averaging marks in the papers within the group.
  2. The Final Score is the simple average of the five Group Scores.

The data for the top ten students are given below. (Dipan’s score in English Paper II is missing.)

Question: 1

How much did Dipan get in English Paper II?

Show Hint

For missing value questions in averages, isolate the unknown and solve step-by-step using the total sum formula.

The Correct Option is C

Solution and Explanation

From the table, Dipan’s Final Score is \(96.0\). The Final Score is the average of five Group Scores: PCB, Mathematics, Social Science, Vernacular, and English.
Dipan’s Group Scores:
- PCB: \((98 + 98 + 98)/3 = 98\)
- Mathematics: 95
- Social Science: \((96 + 95)/2 = 95.5\)
- Vernacular: \((96 + 94)/2 = 95\)
- English: \((96 + x)/2\), where \(x\) is English Paper II.
Final Score equation: \[ \frac{98 + 95 + 95.5 + 95 + \frac{96 + x}{2}}{5} = 96 \] \[ \Rightarrow 383.5 + \frac{96 + x}{2} = 480 \] \[ \frac{96 + x}{2} = 96.5 \quad \Rightarrow \quad 96 + x = 193 \quad \Rightarrow \quad x = 97 \] Thus, English Paper II score is \( \boxed{97} \).

The Correct Option is C

Solution and Explanation

Ram: Yes.
- Ram's marks are compared to the required threshold of ≥95 in each subject:

  • PCB: Ram scored ≥95 in Physics, Chemistry, and Biology.
  • Math: Ram scored ≥95 in Mathematics.
  • Soc. Sci: Ram scored ≥95 in Social Science.
  • Vernacular: Ram scored ≥95 in Vernacular.
  • English: Ram scored ≥95 in English.

Since all the subject marks are ≥95, Ram satisfies the condition.

Dipan: Yes. 
- Dipan's marks are also compared to the required threshold of ≥95 in each subject:

  • PCB: Dipan scored ≥95 in Physics, Chemistry, and Biology.
  • Math: Dipan scored ≥95 in Mathematics.
  • Soc. Sci: Dipan scored ≥95 in Social Science.
  • Vernacular: Dipan scored ≥95 in Vernacular.
  • English: Dipan scored ≥95 in English.

Since all the subject marks are ≥95, Dipan satisfies the condition.

Sagnik: Yes. 
- Sagnik's marks are compared to the required threshold of ≥95 in each subject:

  • PCB: Sagnik scored ≥95 in Physics, Chemistry, and Biology.
  • Math: Sagnik scored ≥95 in Mathematics.
  • Soc. Sci: Sagnik scored ≥95 in Social Science.
  • Vernacular: Sagnik scored ≥95 in Vernacular.
  • English: Sagnik scored ≥95 in English.

Since all the subject marks are ≥95, Sagnik satisfies the condition.

Sanjiv: No. 
- Sanjiv's marks are compared to the required threshold of ≥95 in each subject:

  • PCB: Sanjiv scored ≥95 in Physics, Chemistry, and Biology.
  • Math: Sanjiv scored ≥95 in Mathematics.
  • Soc. Sci: Sanjiv scored ≥95 in Social Science.
  • Vernacular: Sanjiv's Vernacular Paper II score is <95, which fails the requirement for Vernacular.
  • English: Sanjiv scored ≥95 in English.

Since Sanjiv's Vernacular Paper II score is <95, Sanjiv does not satisfy the condition.

Joseph: No. 
- Joseph's marks are compared to the required threshold of ≥95 in each subject:

  • PCB: Joseph scored <95 in Physics, Chemistry, and Biology.
  • Math: Joseph scored ≥95 in Mathematics.
  • Soc. Sci: Joseph scored ≥95 in Social Science.
  • Vernacular: Joseph scored ≥95 in Vernacular.
  • English: Joseph scored ≥95 in English.

Since Joseph's PCB score is <95, Joseph does not satisfy the condition.

Agni: No. 
- Agni's marks are compared to the required threshold of ≥95 in each subject:

  • PCB: Agni scored ≥95 in Physics, Chemistry, and Biology.
  • Math: Agni scored ≥95 in Mathematics.
  • Soc. Sci: Agni scored ≥95 in Social Science.
  • Vernacular: Agni's Vernacular Paper I score is <95, which fails the requirement for Vernacular.
  • English: Agni scored ≥95 in English.

Since Agni's Vernacular Paper I score is <95, Agni does not satisfy the condition.

Pritam: No. 
- Pritam's marks are compared to the required threshold of ≥95 in each subject:

  • PCB: Pritam scored ≥95 in Physics, Chemistry, and Biology.
  • Math: Pritam scored ≥95 in Mathematics.
  • Soc. Sci: Pritam's Social Science Paper I score is <95, which fails the requirement for Social Science.
  • Vernacular: Pritam scored ≥95 in Vernacular.
  • English: Pritam scored ≥95 in English.

Since Pritam's Social Science Paper I score is <95, Pritam does not satisfy the condition.

Conclusion: Exactly 3 boys (Ram, Dipan, and Sagnik) satisfy the condition of having ≥95 in all relevant subjects.

Question: 3

Had Joseph, Agni, Pritam and Tirna each obtained Group Score of 100 in the Social Science Group, their standing in decreasing order of final score would be:

Show Hint

When all are improved in one group, compare the impact of change by original group score — lower original score gets more boost.

The Correct Option is A

Solution and Explanation

Recalculate final scores for each after replacing Social Science Group score with 100:
- Pritam: New average rises significantly (biggest improvement).
- Joseph: Next highest improvement.
- Tirna: Slightly less improvement than Joseph.
- Agni: Least improvement among the four.
Thus, the order is \( \boxed{\text{Pritam, Joseph, Tirna, Agni}} \).

The Correct Option is C

Solution and Explanation

Improving one paper to 100 gives maximum benefit to the student with the largest gap between their lowest paper score and 100, especially if that paper belongs to a group with a low average. Pritam benefits the most, overtaking all others in final score.
