A. 50000
B. 42000
C. 33000
D. 21000

Answer: Option D

2. 

What is the difference between the total productions of the two Companies in the given years ?

A. 19000
B. 22000
C. 26000
D. 28000

Answer: Option C

From the line-graph it is clear that the productions of Company X in the years 1997, 1998, 1999, 2000, 2001 and 2002 are 119000, 99000, 141000, 78000, 120000 and 159000 and those of Company Y are 139000, 120000,100000, 128000, 107000 and 148000 respectively.

Total production of Company X from 1997 to 2002

    = 119000 + 99000 + 141000 + 78000 + 120000 + 159000

    = 716000.

and total production of Company Y from 1997 to 2002

    = 139000 + 120000 + 100000 + 128000 + 107000 + 148000

    = 742000.

Difference = (742000 - 716000) = 26000.

Explanation:

Average number of vehicles manufactured by Company X

    = 1 x (119000 + 99000 + 141000 + 78000 + 120000 + 159000)
6

    = 119333.

For 1999 (141000 - 100000) = 41000.

For 2000 (128000 - 78000) = 50000.

For 2001 (120000 - 107000) = 13000.

For 2002 (159000 - 148000) = 11000.

Clearly, maximum difference was in 2000.
