Hyderabad is req. answer.

5.    Answer  (3) 

6.    Answer: (4)
Required difference = (128000 - 107000) = 21000.

7.    Answer  (3) : 
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.

8.    Answer: (1)

The difference between the productions of Companies X and Y in various years is:
For 1997 (139000 - 119000) = 20000.
For 1998 (120000 - 99000) = 21000.
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
