# Difficult Tabular Data Solved QuestionData Interpretation Discussion

Common Information

In a Class X Board examination, ten papers are distributed over five Groups – PCB, Mathematics, Social Science, Vernacular and English. Each of the ten papers is evaluated out of 100. The final score of a student is calculated in the following manner.

First, the Group Scores are obtained by averaging marks in the papers within the Group. The final score is the simple average of the Group Scores.

The data for the top ten students are presented below. (Dipan’s score in English Paper II has been intentionally removed in the table).

Note: B or G against the name of a student respectively indicates whether the student is a boy or a girl.

 Q. Common Information Question: 1/5 How much did Dipan get in English Paper II?
 ✖ A. 94 ✖ B. 96 ✔ C. 97 ✖ D. 98 ✖ E. 99

Solution:
Option(C) is correct

Dipan’s Group Scores are as follows:

PCB Group:
$= 98 × \dfrac{3}{3}$

$= 98$

Mathematics Group:

$= 95$

Social Science Group:

$= \dfrac{96 + 95}{2}$

$= 95.5$

Vernacular Group:

$= \dfrac{96 + 94}{2}$

$= 95$

Dipan’s final score,

$= 96$

⇒Sum of Dipan’s Group Scores:

$= 96 × 5 = 480$

$⇒ 98 + 95 + 95.5 + 95 + 48 +x/2= 480$

$⇒ x/2 = 48.5$

$⇒ x = 97$

Dipan scored 97 marks in English Paper II.

Hence, option C.
