## Introduction to Data Interpretation

#### Data Interpretation

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. If NHAI could receive a total of Rs. 9,695 crores as External Assistance, by what per cent (approximately) should it increase the Market Borrowing to arrange for the shortage of funds?

1. Difference = \$ (11486 – 9695) billion
= \$ 1791 billion
If increase be x%, then

 29952 × x = 1791 100

 ⇒ X = 179100 ≈ 6% 29952

##### Correct Option: C

Difference = \$ (11486 – 9695) billion
= \$ 1791 billion
If increase be x%, then

 29952 × x = 1791 100

 ⇒ X = 179100 ≈ 6% 29952

1. If the toll is to be collected through an outsourced agency by allowing a maximum 10% commission, how much amount should be permitted to be collected by the outsourced agency, so that the project is supported with \$ 4,910 billion?

1. If the amount permitted be \$ x then,

 X × 100 = 4910 110

 ⇒ X = 4910 × 110 = \$ 5401 billion 100

##### Correct Option: C

If the amount permitted be \$ x then,

 X × 100 = 4910 110

 ⇒ X = 4910 × 110 = \$ 5401 billion 100

Direction: Study the following graph carefully and answer the given questions.

1. The number of A-type employees in 1998 was approximately what per cent of the number of A-type employees in 1997?

1. Number of A-type employees : Year 1997

 ⇒ 42980 × 20 = 8596 100

Year 1998 ⇒ 10700
∴ Required percent
 = 10700 × 100 ≈ 125 8596

##### Correct Option: D

Number of A-type employees : Year 1997

 ⇒ 42980 × 20 = 8596 100

Year 1998 ⇒ 10700
∴ Required percent
 = 10700 × 100 ≈ 125 8596

1. If the number of D type employees in 1998 was 5000, what would have been its approximate percentage in the company?

1. Required per cent

 = 5000 × 100 ≈ 10 48640

##### Correct Option: A

Required per cent

 = 5000 × 100 ≈ 10 48640

1. What was the approximate difference in the number of B type of employees during 1997 and 1998?

1. Required difference

 = 48640 × 10 - 42980 × 6 100 100

= 4864 – 2579 = 2285

##### Correct Option: A

Required difference

 = 48640 × 10 - 42980 × 6 100 100

= 4864 – 2579 = 2285
