## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie chart, given here, shows the amount of money spent on various sports by a school administration in a particular year. 1. If the money spent on football was \$ 9,000 how much more money was spent on hockey than on football?

1. ∵ 45° ≡ \$ 9000
Angle of diff. of money spent on Hockey and Football = 55°

 ∴ 55° ≡ 9000 × 55° = \$ 11000 45°

##### Correct Option: A

∵ 45° ≡ \$ 9000
Angle of diff. of money spent on Hockey and Football = 55°

 ∴ 55° ≡ 9000 × 55° = \$ 11000 45°

Direction: The pie chart, given here, represents the number of valid votes obtained by four students who contested election for school leadership. The total number of valid votes polled was 720.
Observe the chart and answer the questions based on it. 1. By how many votes did the winner defeat his nearest rival?

1. Angle of the difference of votes of the winner and the nearest rival = 120 – 100 = 20°
∴ 360° ≡ 720

 ∴ 20° ≡ 720 × 20 = 40 360

##### Correct Option: A

Angle of the difference of votes of the winner and the nearest rival = 120 – 100 = 20°
∴ 360° ≡ 720

 ∴ 20° ≡ 720 × 20 = 40 360

1. Who was the winner?

1. Sivaraman got the maximum votes. i.e.

 720 × 120 = 240 votes 360

∴ He was the winner.

##### Correct Option: A

Sivaraman got the maximum votes. i.e.

 720 × 120 = 240 votes 360

∴ He was the winner.

1. What was the minimum number of votes obtained by any candidate?

1. Yasin got the minimum votes.
∵ 360° o 720

 ∴ 60° ≡ 720 × 60 = 120 360

##### Correct Option: C

∵ 360° o 720

 ∴ 60° ≡ 720 × 60 = 120 360

Direction: The pie chart given here shows the breakup of the cost of construction of a house on various heads. Study the chart and answer the questions. 1. Out of the total cost (\$ 15,00,000) of construction how much amount of money was spent on labour and supervision combined together?

1. Corresponding angle of labour and supervision combined
= 90° + 54° = 144°
∵ 360° ≡ 1500000

 ∴ 144° ≡ 1500000 × 144 360

= \$ 600000

##### Correct Option: C

Corresponding angle of labour and supervision combined
= 90° + 54° = 144°
∵ 360° ≡ 1500000

 ∴ 144° ≡ 1500000 × 144 360

= \$ 600000
