Answers with explanation:

1.(d)Required difference = 50 – 45 =  5 lakh tonne
= 5,00,000 tonnes

2.(a)Required percentage = (55 – 40)/40 * 100
= 75/2 = 37.5%

3.(b) In 2001 =(60 -50)/60 * 100 = 16.66%

4.(d)Required percentage = (60 + 60)/(50 + 40) * 100
120/90 * 100 = 133.33%

5.(c)Average production of company A
= (50 + 40 + 55 + 45 + 60 + 50)/6
= 300/6 = 50 lakh tonnes
Average production of company B
= (55 + 60 + 50 + 55 + 50 + 55)/6
= 325/6 = 54.17 lakh tones
Average production of company C
= (45 + 50 + 60 + 60 + 45 + 40)/6
= 300/6 = 50 lakh tones
Required difference = 54.17 – 50
= 4.17 lakh  tones

6.(d)

7. (a) Percentage increase in 1996=(60 -40)/40 * 100 = 50%

8.(d)Average production per year for company B=(50 + 55 + 45 + 70 + 50 + 60 + 80)/7 =410/7
Average production per year for company C=(55 + 40 + 60 + 75 + 60 + 80 + 70)/7  =440/7
Required Percentage
= 410/440 * 100 =  93%

9.(b)Required Percentage = (75 – 60)/60 * 100 = 25%

10.(b)Required difference
= (80 + 70 + 60)/3 – (60 + 55 + 50)/3
= 210/3 – 165/3 = 70 – 55
15 thousand tonnes
