Data Interpretation Concepts

Q. 1 The table below shows the number of employees in five different departments over three years. Answer the following question:
Department202120222023
HR120135150
Sales200180190
IT250260270
Marketing150140145
Finance100110120

What is the percentage increase in the total number of employees from 2021 to 2023?

(a) 10%
(b) 15%
(c) 6.71%
(d) 14%

Check Solution

Ans: (c) 6.71%

Find the percentage increase:

$\text{Percentage Increase} = \frac{\text{875} – \text{820}}{\text{820}} \times 100 = \frac{55}{820} \times 100 \approx 6.71\%$

Q. 2 A company’s annual budget is distributed across five departments:

The total budget is $2,000,000. What is the budget allocated to the Marketing department?

(a) 200,000
(b) 300,000
(c) 150,000
(d) 250,000

Check Solution

Ans: (b) $300,000

Step 1: Marketing’s percentage share is 15%.
Step 2: Total budget = 2,000,000.
Marketing budget = $15\% \times 2,000,000 = 300,000$

Q. 3 The bar graph below shows the production (in tons) of three crops: Wheat, Rice, and Maize over four years.

What is the average production of Maize over the four years?

(a) 275 tons
(b) 300 tons
(c) 325 tons
(d) 250 tons

Check Solution

Ans: (a) 275 tons

Step 1: Add up the total production of Maize over the years.

  • Maize production: 200+250+300+350=1100

Step 2: Calculate the average:

$\text{Average Production} = \frac{\text{Total Production}}{\text{Number of Years}} = \frac{1100}{4} = 275$

Q. 4 A company’s quarterly profits (in $1000) for the years 2022 and 2023 are as follows:
QuarterQ1Q2Q3Q4
2022 Profit25303540
2023 Profit30354045

What is the percentage increase in total annual profit from 2022 to 2023?

(a) 10%
(b) 15%
(c) 20%
(d) 25%

Check Solution

Ans: (b) 15%

Step 1: Calculate the total annual profits for 2022 and 2023.

  • 2022: 25+30+35+40=130
  • 2023: 30+35+40+45=150

Step 2: Find the percentage increase:

$\text{Percentage Increase} = \frac{\text{150} – \text{130}}{\text{130}} \times 100 = \frac{20}{130} \times 100 = 15.38\%$

Q. 5 A survey shows the percentage distribution of different modes of transport used by people in a city. If the total population surveyed is 20,000, How many people use the train as their primary mode of transport?

(a) 4000
(b) 5000
(c) 6000
(d) 7000

Check Solution

Ans: (b) 5000

Step 1: Total population = 20,000. Train users = 25%.

$\text{Number of Train Users} = 25\% \times 20000 = 0.25 \times 20000 = 5000$

Q. 6 A retail chain operates in five cities and records monthly sales (in $1000):
CityJanuaryFebruaryMarch
City A120130140

What is the total sales in March across all cities?

(a) $610,000
(b) $640,000
(c) $650,000
(d) $600,000

Check Solution

Ans: (a) $610,000

Step 1: Add the sales for all cities in March:

  • 140+170+120+95+85=610 (in $1000)

Step 2: Convert to dollars: $610 \times 1000 = 610,000$

Q. 7 The table below shows the cost of raw materials (in $) for three companies over four years.
YearCompany XCompany YCompany Z
2020150014001300
2021160015001400
2022165015501450

Which company had the highest percentage increase in raw material costs from 2020 to 2023?

(a) Company X
(b) Company Y
(c) Company Z
(d) All had the same increase

Check Solution

Ans: (c) Company Z

Step 1: Calculate percentage increases for each company:

  • Company X: $\frac{1700 – 1500}{1500} \times 100 = \frac{200}{1500} \times 100 = 13.33\%$
  • Company Y: $\frac{1600 – 1400}{1400} \times 100 = \frac{200}{1400} \times 100 = 14.29\%$
  • Company Z: $\frac{1500 – 1300}{1300} \times 100 = \frac{200}{1300} \times 100 = 15.38\%$

Step 2: Compare the increases.
Company Z has the highest increase.

Q. 9 The data below shows the distribution of ages in a community:
0–10 years: 100
11–20 years: 200
21–30 years: 150
31–40 years: 250
Above 40 years: 300
What percentage of the population is aged 31 years or above?

(a) 60%
(b) 55%
(c) 70%
(d) 75%

Check Solution

Ans: (b) 55%

Step 1: Add the population aged 31 or above:

  • 250+300=550. Total population = 100+200+150+250+300=1000

Step 2: Calculate the percentage:

$\text{Percentage} = \frac{550}{1000} \times 100 = 55\%$
