Total production by unit B in 2001 and 2002 together = (75 + 60) = 135 Million tons
Total production by unit C in 2001 and 2002 together = (100 + 110) = 210 Million tons
? Required ratio = (135:210) = 9:14.
As we can see in the graph that
Total production by unit C, D and E in year 2001 and 2002 together = (100 + 110 + 95 + 100 + 85 + 105 )
Required total production = (100 + 110 + 95 + 100 + 85 + 105) = 595 Million tons.
As we can see in the graph that
Total production by unit F in year 2001 and 2002 together = ( 70 + 85 ) = 155 Million tons
Similarly
Total production by unit D in year 2001 and 2002 together = ( 95 + 100 ) = 195 Million tons
? Required percentage = (Total production by unit F in year 2001 and 2002 together x 100 / Total production by unit D in year 2001 and 2002 together )
? Required percentage = ( 155 x 100 / 195 )
=79.487 ? 79.49
Average production of A = 50
Average production of B = 54.17
Average production of C = 50
Difference of production = 54.17 ? 50 = 4.17.
Difference of production of C in 1991 and A in 1996 = Production of company A in 1996 - Production of company C in 1991
Difference of production of C in 1991 and A in 1996 = ( 50 - 45 ) million tonnes = 5 x 1000000 = 5000000 ( Since 1 million = 10 lacks )
