## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following pie-chart shows the monthly expenditure of a family on food, house rent, clothing, education, fuel and miscellaneous. Study the pie-chart and answer the questions. 1. If the expenditure on fuel is \$ 3000, the total expenditure excluding expenditure on house rent and education is

1. Percentage expenditure on house rent + education = 38%
Remaining expenses = 100 – 38 = 62%
∵ 15% ≡ \$ 3000

 ∴ 62% ≡ 3000 × 62 15

= \$ 12400

##### Correct Option: C

Percentage expenditure on house rent + education = 38%
Remaining expenses = 100 – 38 = 62%
∵ 15% ≡ \$ 3000

 ∴ 62% ≡ 3000 × 62 15

= \$ 12400

1. The central angle of the sector for the expenditure on fuel (in degrees) is

1. ∵ 100% ≡ 360°

 ∴ 1% ≡ 360 100

 ∴ 15% ≡ 360 × 15 = 54° 100

##### Correct Option: B

∵ 100% ≡ 360°

 ∴ 1% ≡ 360 100

 ∴ 15% ≡ 360 × 15 = 54° 100

1. If the expenditure for food is \$ 9000, then the expenditure for education is

1. ∵ 30% ≡ Rs. 9000

 ∴ 1% ≡ 9000 30

 ∴ 18% ≡ 9000 × 18 30

= Rs. 5400

##### Correct Option: C

∵ 30% ≡ Rs. 9000

 ∴ 1% ≡ 9000 30

 ∴ 18% ≡ 9000 × 18 30

= Rs. 5400

Direction: Study the pie-chart and table given below and answer the questions. 1. The ratio of number of males in Marketing department to the number of females working in that department is

1. Total employees in Marketing department = 192
Males = 165
Females = 192 – 165 = 27
∴ Required ratio = 165 : 27
= 55 : 9

##### Correct Option: D

Total employees in Marketing department = 192
Males = 165
Females = 192 – 165 = 27
∴ Required ratio = 165 : 27
= 55 : 9

1. The percentage of females working in IT department to the total number of employees working in the organization is

1. Number of employees in IT department

 = 800 × 20 = 160 100

Number of females
= 160 – 74 = 86
∴ Required percentage
 = 86 × 100 800

= 10.75

##### Correct Option: B

Number of employees in IT department

 = 800 × 20 = 160 100

Number of females
= 160 – 74 = 86
∴ Required percentage
 = 86 × 100 800

= 10.75
