Study the given chart and answer the question.
The percentage increase in the number of workers in 2016 is maximum as compared to that in 2015 in case of workers of type:
Answer & explanation
Correct answer: option 2
For A ,
Number of workers in 2015 = 100
Number of workers in 2016 = 200
Increased percentage in number of workers in 2016 comparative to 2015 = \(\frac{200-100}{100 }\) × 100
= \(\frac{100}{100 }\) × 100
= 100%
For B,
Number of workers in 2015 = 50
Number of workers in 2016 = 270
Increased percentage in number of workers in 2016 comparative to 2015 = \(\frac{270-50}{50 }\) × 100
= \(\frac{220}{50 }\) × 100
= 440%
For C,
Number of workers in 2015 = 220
Number of workers in 2016 = 300
Increased percentage in number of workers in 2016 comparative to 2015 = \(\frac{300-220}{220 }\) × 100
= \(\frac{80}{220 }\) × 100
= 36.36%
For D,
Number of workers in 2015 = 150
Number of workers in 2016 = 200
Increased percentage in number of workers in 2016 comparative to 2015 = \(\frac{200-150}{150 }\) × 100
= \(\frac{50}{150 }\) × 100
= 33.33%
So , maximum percentage increase is for B.
