## Introduction to Data Interpretation

#### Data Interpretation

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 cement, steel and supervision is what per cent of the total cost of construction?

1. Required per cent

 = 100 × (72° + 54° + 54°) 360

 = 100 × 180° = 50 per cent 360

##### Correct Option: C

Required per cent

 = 100 × (72° + 54° + 54°) 360

 = 100 × 180° = 50 per cent 360

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

1. Difference (%)

 = 100 × 90 % - 100 × 54 % 360 360

= 25% – 15%
= 10% of the total cost

##### Correct Option: B

Difference (%)

 = 100 × 90 % - 100 × 54 % 360 360

= 25% – 15%
= 10% of the total cost

1. The amount spent on cement is

1. Amount spent on cement

 = 100 × 72 % of 600000 360

 = 20 × 600000 = 1,20,000 100

##### Correct Option: C

Amount spent on cement

 = 100 × 72 % of 600000 360

 = 20 × 600000 = 1,20,000 100

Direction: The Pie chart given here represents the domestic expenditure of a family in per cent. Study the chart and answer the following questions if the total monthly income of the family is \$ 33,650.

1. Had there been no children in the family what would have been the total savings of the family including that provident fund?

1. Expenditure on children = 23%
Provident fund savings = 12%
For no children, total savings = 35%
∴ Required savings = 35% of \$ 33650

 = \$ 35 × 33650 = \$ 11777.50 100

##### Correct Option: D

Expenditure on children = 23%
Provident fund savings = 12%
For no children, total savings = 35%
∴ Required savings = 35% of \$ 33650

 = \$ 35 × 33650 = \$ 11777.50 100

1. The total amount per month, the family spends on food and entertainment combined together, is :

1. Amount spent on food and entertainment together = 34% of \$ 33650

 = \$ 34 × 33650 = \$ 11441 100

##### Correct Option: B

Amount spent on food and entertainment together = 34% of \$ 33650

 = \$ 34 × 33650 = \$ 11441 100
