Directions (1-5):

In 2011= (80/60)*100=133.3%

In 2012= (45/65)*100=69.2%

In 2013= (65/50)*100=130%

In 2014= (65/55)*100=118.2%

In 2015= (55/70)*100=78.5%

From the graph,

Required difference= 80 lakh tones- 65 lakh tones

= 15 lakh tones

Total production in the given period of company A = 60 + 65 + 50 + 55

= 230

Required average production of company A = 230/4 = 57.5

Total production in the given period of company C = 55 + 75 + 70 + 45 = 245

Required average production of company C = 245/4 = 61.25

Required ratio = 61.25: 57.5

ย = 49: 46

Average production of company A in the given period= (60+65+50+55+70)/5

= 60

Average production of company B in the given period= (80+45+65+65+55)/5

= 62

Average production of company C in the given period= (55+75+70+45+60)/5

= 61

Thus the company B has the maximum average

Required percentage increase from 2011 to 2013 = [(70 – 55)/55] * 100

= 15/55 * 100

= 27%
