## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie- chart given here shows expenditures incurred by a family on various items and their savings, which amounts to \$ 8,000 in a month. Study the chart and answer the questions based on the pie-chart

1. What is the total expenditure of the family for the month?

1. Total expenditure

 = 8000 × (105 + 120 + 45 + 30) 60

 = 8000 × 300 60

##### Correct Option: A

Total expenditure

 = 8000 × (105 + 120 + 45 + 30) 60

 = 8000 × 300 60

1. The ratio of the expenditure on food to the savings is

1. Ratio of degree of expenditure on food to savings = 120° : 60°
= 2 : 1

##### Correct Option: B

Ratio of degree of expenditure on food to savings = 120° : 60°
= 2 : 1

1. How much expenditure is incurred on education?

1. ∵ 60° ≡ \$ 8000
∴ Expenditure on Education

 = 30 × 8000 = \$ 4,000 60

##### Correct Option: C

∵ 60° ≡ \$ 8000
∴ Expenditure on Education

 = 30 × 8000 = \$ 4,000 60

Direction: The pie- chart given below shows the marks obtained by a student in an examination.
If the total marks obtained by him in the examination were 540, answer the questions given below based on this pie chart.

1. How many marks were obtained by the student in Science?

1. Corresponding angle for science = 80°
∵ 360° ≡ 540

 ∴ 80° ≡ 540 × 80 = 120 360

##### Correct Option: B

Corresponding angle for science = 80°
∵ 360° ≡ 540

 ∴ 80° ≡ 540 × 80 = 120 360

1. How many more marks were obtained by the student in Maths than those in Hindi?

1. Difference of corresponding angles = 90° – 70° = 20°
∵ 360° ≡ 540

 ∴ 20° ≡ 540 × 20 = 30 360

##### Correct Option: A

Difference of corresponding angles = 90° – 70° = 20°
∵ 360° ≡ 540

 ∴ 20° ≡ 540 × 20 = 30 360
