Given below is a pie chart depicting the reason given by people who had injured their lower back.
Study the pie chart and find the number of people who injured their back while either bending and lifting. A total of 600 people were surveyed.
Solution:
From the pie chart, we read that
The total number of people can be given as (18% + 49%) = 67% of 600.
Total percentage of people who injured their back while
bending and lifting = 18% +49% = 67%.
Number of people who injured their back while bending and lifting
= 67% of 600
= 67/100 × 600
= 402
Hence, 402 people injured their back while bending and lifting.
✦ Try This: Given below is a pie chart depicting the reason given by people who had injured their lower back. Study the pie chart and find the number of people who injured their back by other reasons. A total of 600 people were surveyed.
Total percentage of people who injured their backs for reasons other than bending and lifting
= 12% + 12% + 9%
= 33%
Number of such people = 33% of 600 = 33/100× 600= 198
