6. (4) in 1999, average employment per factory is greater than 1998 and less than 2000.
7. (2), in 1996, for 20100 factories , employees = 13,245,900; average = 609, total employees = 18,361,350. So average for remaining factories = 509.
8. (1) , total employment in 1999= 36240 x 736.
Total employment in 1996 = 609 x 30150,
Ratio = (36240×736)/(30150×609)=1.45
9. (4) From the figure it can be seen that the maximum increase in the number of factories is in 1995-2000.
10. (4) , we do not have year wise data in between 1975- 1980 & similarly between 1980-1985,etc.
