## Introduction to Data Interpretation

#### Data Interpretation

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

1. Expenditure incurred on timber is what per cent of the expenditure on cement?

1. Required percentage

 = 36 × 100 = 50% 72

##### Correct Option: B

Required percentage

 = 36 × 100 = 50% 72

1. The total expenditure incurred on bricks, steel and cement is what per cent of the total cost of construction?

1. Corresponding angle on the expenditure on bricks, steel and cement
= 54 + 54 + 72 = 180°
∵ 360° ≡ 100%

 ∴ 180° ≡ 100 × 180 = 50% 360

##### Correct Option: A

Corresponding angle on the expenditure on bricks, steel and cement
= 54 + 54 + 72 = 180°
∵ 360° ≡ 100%

 ∴ 180° ≡ 100 × 180 = 50% 360

1. If the total cost of construction of the house is \$ 15,00,000, how much amount of money was spent on labour?

1. Corresponding angle of labour = 90°

 Clearly, 90° = 1500000 × 90 360

= \$ 375000

##### Correct Option: D

Corresponding angle of labour = 90°

 Clearly, 90° = 1500000 × 90 360

= \$ 375000

Direction: The pie graph given here shows the break-up of the cost of construction of a house. Assuming that the total cost of construction is \$ 6,00,000, answer the questions.

1. The amount spent on labour exceeds the amount spent on supervision by

1. Differences in percentage

 = 100 × 90° - 100 × 54° % 360° 360°

∴ Required difference
 = 600000 10 = \$ 60,000 100

##### Correct Option: D

Differences in percentage

 = 100 × 90° - 100 × 54° % 360° 360°

∴ Required difference
 = 600000 10 = \$ 60,000 100
