## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following table carefully and answer the questions given below it.

1. Mr X wants to travel a distance of 8 Km by Type A vehicle. How much more money will be required to be spent if he decides to travel by Type B vehicle instead of Type A?

1. ∴ Difference = Fare by B − Fare by A

##### Correct Option: B

 Fare, for 8 Km by A = 13.50 + 17.25 - 13.50 = 13.50 + 3.75 = \$ 14.75 10 - 7 3

 Fare by B = 24.25 + 33.25 - 24.25 = \$ 27.25 3

∴ Difference = Fare by B − Fare by A
Difference = 27.25 − 14.75 = \$ 12.50.

Direction: The pie- chart given below shows expenditure incurred by a family on various items and their savings. Study the chart and answer the questions based on the pie- chart

1. If the monthly income is \$ 36000, then the yearly savings is :

1. ∵ 360° ≡ \$ 36000

 ∴ 1° ≡ 36000 = \$ 100 360

∴ 60° ≡ 60 × 100 = \$ 6000
∴ Annual savings = \$ (6000 × 12)
= \$ 72000

##### Correct Option: B

∵ 360° ≡ \$ 36000

 ∴ 1° ≡ 36000 = \$ 100 360

∴ 60° ≡ 60 × 100 = \$ 6000
∴ Annual savings = \$ (6000 × 12)
= \$ 72000

1. If the expenditure on education is \$ 1600 more than that on housing, then the expenditure on food is :

1. ∵ 70° – 54° ≡ \$ 1600
∵ 16° ≡ \$ 1600

 ∴ 1° ≡ 1600 = \$ 100 16

∴ 120° ≡ 120 × 100
= \$ 12000

##### Correct Option: A

∵ 70° – 54° ≡ \$ 1600
∵ 16° ≡ \$ 1600

 ∴ 1° ≡ 1600 = \$ 100 16

∴ 120° ≡ 120 × 100
= \$ 12000

1. The ratio of expenditure on food to savings is :

1. Expenditure on food : savings
= 120° : 60° = 2 : 1

##### Correct Option: D

Expenditure on food : savings
= 120° : 60° = 2 : 1

Direction: The following pie-chart shows the sources of funds (In \$ billion) to be collected by the National Highways Authority of India (NHAI) for its Phase II projects. Study the pie-chart and answer the following Three questions :

1. The central angle corresponding to Market Borrowing is

1. Total funds = Rs. (11486 + 5252 + 4910 + 6000 + 29952) billion
= \$ 57600 billion
\$ 57600 ≡ 360°

 ∴ 29952 ≡ 360 × 29952 57600

= 187.2°

##### Correct Option: C

Total funds = Rs. (11486 + 5252 + 4910 + 6000 + 29952) billion
= \$ 57600 billion
\$ 57600 ≡ 360°

 ∴ 29952 ≡ 360 × 29952 57600

= 187.2°
