On the basis of given graph in question ,
Gross profit in Year 1994 = 30
Net profit in Year 1994 = 10
Ratio = 30 : 10
Gross profit : net profit in Year 1994 ⇒ 3 : 1
Gross profit in Year 1995 = 40
Net profit in Year 1995 = 15
Gross profit : net profit in Year 1995 ⇒ 40 : 15 = 8 : 3
Gross profit in Year 1996 = 45

From the given bar diagram , we see
Total production of Company X = 300 + 450 + 250 + 500 + 400 = 1900
Number of years = 5Average production of Company X = Total production of Company X Number of years Average production of Company X = 1900 = 380 thousand tonnes 5
Total production of Company Y = 250 + 350 + 350 + 400 + 500 = 1850
Number of years = 5Average production of Company Y = Total production of Company Y Number of years Average production of Company Y = 1800 = 370 thousand tonnes 5
Total production of Company Z = 350 + 400 + 450 + 350 + 350 = 1900
Number of years = 5Average production
of Company Z =Total production of Company Z Number of years
Correct Option: A
From the given bar diagram , we see
Total production of Company X = 300 + 450 + 250 + 500 + 400 = 1900
Number of years = 5Average production of Company X = Total production of Company X Number of years Average production of Company X = 1900 = 380 thousand tonnes 5
