A company starts constructing buildings for a college. The constructions have 4 stages.
1. buildings proposals
2. proposals approval
3. constructions implemented
4. buildings completed
The above 3D-bar graph indicates the status of constructions for 4 years 2015 to 2018.
The X-axis scale 0, 2,4,6,8,10 indicates 0, 20%, 40%, 60%, 80%, 100%.
Study the bar graph carefully and answer the following question.
Find the total percentage of buildings completed during the total period, 2015 to 2018.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 50%.
Total period = 2015 to 2018
Stages of construction = 4
Stage 4 (Buildings completed) percentages for each year:
2015: 20%
2016: 10%
2017: 10%
2018: 10%
Total percentage of buildings completed = Sum of percentages for each year
⇒ Total percentage of buildings completed = 20% + 10% + 10% + 10%
⇒ Total percentage of buildings completed = 50%
∴ The total percentage of buildings completed during the period 2015 to 2018 is 50%.
