2) Answer (c)
approximate % increase in output of Mill sector in 2007-08 compared to previous year=
1781-1746/1746*100%=2%

3.56, 3.38 ,3.36, 3.32, 3.27, 3.17, 3.26
thus, in no year the % is greater than 4.∴ statement 1 is correct.
The ratio of mill sector to handloom in 2004-05 and 2005-06 are 26.67% and 27.1% respectively.∴ Statement 2 is also correct.Thus, option C is the right choice.
Hence, option C is the correct choice.

4) Answer (b)
percentage loss in 2008-09=(56025-54966)/56025 ×100=1.89%
the percentage loss in 2009-10 is 1.89%
=> the fabric production in 2009-10=98.11% of 54966=53927.68≅= 53927
