Study the pie-chart and answer the options: Break up (degree wise) of students in terms of specialization in different areas (A, B, C, D & E) in an MBA program. The total number of students specialising in A and B exceeds the total number of students specialising in C and D by x, which lies between: Correct Answer 60 and 65

Given:

Total number of students = 2100

Difference between students in A and B and students in C and D = x

Calculation:

Angle of the students specialising in A and B = 61.2° + 75.6° = 136.8° 

Angle of the students specialising in C and D = 72° + 54° = 126° 

Angle difference = 136.8° – 126° = 10.8°

360° = 2100

⇒ 1° = 2100/360 = 210/36

⇒ 1° = 210/36

⇒ 10.8° = 210/36 × 10.8

⇒ 10.8° = 2268/36

⇒ 10.8° = 63

⇒ x = 63

∴ The total number of students specializing in A and B exceeds the total number of students specializing in C and D by x, which lies between 60 and 65.

The number of students taking admission in First Year of a Degree Course at a college in areas of Social Sciences in 2012 was as follows: Economics (S1) - 96, Psychology (S2) - 84, History (S3) - 160. Political Science (S4) - 120. Sociology (S5) - 125. The break-up of students in different subjects has been presented through the given pie chart. Study the pie chart and answer the question that follows. In 2013, 20% of the Sociology students, 25% of the Political Science students, and one-sixth of the Economics students shifted to another college, and the number of History students got increased by 10% due to students shifting from other colleges. Over and above this, 10% of the remaining Sociology students and one-seventh of the Psychology students got transferred to Economics. What will be the central angle (to the nearest degree) of the sector corresponding to History in the pie chart, representing the break-up in 2013?
