Introduction to Data Interpretation

Direction: The pie-chart given below shows the number of students enrolled in a school in different activities. Total number of students in the school is 1200.
Study the chart and answer the questions.

1. How many students are enrolled in N.C.C. activities?

1. Students enrolled in NCC activities

 = 1200 × 15 = 180 100

Correct Option: A

Students enrolled in NCC activities

 = 1200 × 15 = 180 100

Direction: The follow- ing pie-chart shows the number of students who failed in different subjects in an examination. Examine the chart and answer the following questions. The total number of students who have failed is 500.

1. The percentage of students who have failed in mathematics and language is :

1. Required percentage = 30 + 36 = 66%

Correct Option: C

Required percentage = 30 + 36 = 66%

1. Number of students who failed in mathematics is less than the students who did not qualify in languages by :

 = 500 × 6 = 30 100

Correct Option: C

 = 500 × 6 = 30 100

1. Total number of students who did not qualify in Mathematics and Language and Science, is :

1. Percentage of failure in Maths, Language and Science = 30 + 36 + 32 = 98%
∴ Required no. of students

 = 500 × 98 = 490 100

Correct Option: B

Percentage of failure in Maths, Language and Science = 30 + 36 + 32 = 98%
∴ Required no. of students

 = 500 × 98 = 490 100

1. The central angle of the sector for the students who have failed in mathematics is :

1. ∵ 100% ∴ 360°

 ∴ 30% ≡ 360 × 30 = 108° 100

Correct Option: D

∵ 100% ∴ 360°

 ∴ 30% ≡ 360 × 30 = 108° 100
