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:

B

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.
