Solutions

Answer 1.   (Option D)
Required Percentage = Appeared in Agriculture in 2005 / Qualified  in Arts in 2004 × 100
                                  = 490 / 250 × 100
                                  = 200%

Answer 2.   (Option C)
Percentage drop from 2004 to 2005 = Value (2005) - Value (2004) / Value (2004) × 100
                                                         = 50 / 500 × 100 
                                                         =  10%

Answer 3.   (Option E) (None of These)

Answer 4.   (Option C)
Here, Qualified / Appeared is to be found out and this ratio < 1, so it will be better to apply reverse operation as Appeared / Qualified. The least of such value obtained will give the maximum desired value so, in engineering discipline.
di

Hence % of Qualified / Appeared will be maximum in 2006
Do not try to calculate the (Qualified / Appeared × 100), apply reverse operation and easily find out the ratio.


Answer 5.   (Option C)
Now we here also apply reverse operation Appeared / Qualified 

di set
Hence required percentage is maximum in 2005.
