## Introduction to Data Interpretation

#### Data Interpretation

Direction: In the following questions, study the two pie- charts and answer the questions. 1. The ratio of amount spent for savings in April month’s salary and miscellaneous in May month’s salary is :

1. Required ratio

 = 24000 × 18 : 25000 × 2 100 100

= 24 × 18 : 25 × 2
= 216 : 25

##### Correct Option: A

Required ratio

 = 24000 × 18 : 25000 × 2 100 100

= 24 × 18 : 25 × 2
= 216 : 25

1. What is the per cent increase in Education in May month than April month?

1. Expenditure on education in April

 = 24000 × 47 = \$ 11280 100

Expenditure on education in May
 = 25000 × 50 47 = \$ 12500 100

Percentage increase
 = 12500 - 11280 47 × 100 11280

= 10.82%

##### Correct Option: D

Expenditure on education in April

 = 24000 × 47 = \$ 11280 100

Expenditure on education in May
 = 25000 × 50 47 = \$ 12500 100

Percentage increase
 = 12500 - 11280 47 × 100 11280

= 10.82%

Direction: In the following questions, the pie-chart shows the number of students admitted in different faculties of a college.
Study the chart and answer the questions. 1. If 1000 students are admitted in science, what is the total number of students?

1. ∵ 100° ≡ 1000

 ∴ 360° ≡ 1000 × 360 = 3600 100

##### Correct Option: C

∵ 100° ≡ 1000

 ∴ 360° ≡ 1000 × 360 = 3600 100

1. If 1000 students are admitted in science, what is the ratio of students in science and arts?

1. Required ratio
= 100 : 120
= 5 : 6

##### Correct Option: D

Required ratio
= 100 : 120
= 5 : 6

1. How many students are more in commerce than in law if 1000 students are in science?

1. Difference between the students of commerce and science = 200
[∵ 100° &rquvi; 1000
∴ 1° ≡ 10
∴ 20° ≡ 200]

##### Correct Option: A

Difference between the students of commerce and science = 200
[∵ 100° &rquvi; 1000
∴ 1° ≡ 10
∴ 20° ≡ 200]
