## Introduction to Data Interpretation

#### Data Interpretation

Direction: In the following questions, study the two pie- charts and answer the questions.

1. From the salary of May, the amount spent on Grocery and Electricity are:

1. Expenditure on grocery

 = 25000 × 14 = \$ 3500 100

Expenditure on electricity
 = 25000 × 9 = \$ 2250 100

##### Correct Option: C

Expenditure on grocery

 = 25000 × 14 = \$ 3500 100

Expenditure on electricity
 = 25000 × 9 = \$ 2250 100

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
