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%
2) Answer: e)
From the graph,
Required difference= 80 lakh tones- 65 lakh tones
= 15 lakh tones
3) Answer: e)
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
 = 49: 46
4) Answer: b)
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
5) Answer: c)
Required percentage increase from 2011 to 2013 = [(70 – 55)/55] * 100
= 15/55 * 100
= 27%
