## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following pie-chart shows the preference of musical instruments of 60,000 people surveyed over whole India. Examine the chart and answer the questions.

1. If 2100 people be less from the number of people who prefer Flute, the percentage of people who prefer Flute would have been :

1. People who prefer flute

 = 60000 × 11 = 6600 100

New number of people who prefer flute = 6600 – 2100 = 4500
∴ New percentage
 = 4500 ×100 = 7.5 % 60000

##### Correct Option: C

People who prefer flute

 = 60000 × 11 = 6600 100

New number of people who prefer flute = 6600 – 2100 = 4500
∴ New percentage
 = 4500 ×100 = 7.5 % 60000

Direction: The following pie-chart shows the expenditure incurred on the construction of a house in a city.
Study the chart and answer the following questions.

1. Of the total expenditure, the percentage of expenditure on steel and bricks together is

1. Required percent

 = 36 + 54 × 100 = 25% 360

##### Correct Option: C

Required percent

 = 36 + 54 × 100 = 25% 360

1. What part of expenditure on labour is in respect of total expenditure?

1. ∵ 360° ≡ 1

 ∴ 90 ° ≡ 90 = 1 360 4

##### Correct Option: C

∵ 360° ≡ 1

 ∴ 90 ° ≡ 90 = 1 360 4

1. The highest expenditure in percentage is

1. ∵ 360° ≡ 100%

 ∴ 108 % ≡ 100 × 108 = 30% 360

##### Correct Option: B

∵ 360° ≡ 100%

 ∴ 108 % ≡ 100 × 108 = 30% 360

1. The ratio of expenditure on Steel, Cement and Bricks is

1. Required ratio
= 36 : 72 : 54
= 2 : 4 : 3

##### Correct Option: A

Required ratio
= 36 : 72 : 54
= 2 : 4 : 3
