Solutions

S1. Ans.(c)
Sol. Total number of Girls who appeared in 2007 = 1000/100 * 36 = 360
Total number of Girls who passed in 2007 = 500/100 * 55 = 275
Total number of Girls who failed = 360 – 275 = 85

S2. Ans.(a)
Total number of girls passed in 2009 = 288
Total number of boys failed in 2009 = 770 – 512 = 258

S3. Ans.(e)
Sol. Total number of boys who appeared in all 5 years = 2925
Total number of boys who passed in all 5 years = 1739
Total difference = 2925 – 1739 = 1186

S4. Ans.(c)
Sol. Required Ratio = 770 : 330 = 7:3

S5. Ans.(b)
Sol. Number of boys passed in 2005 = 480
Number of girls appeared in 2006 = 400
Req % = (480 - 400)/400 * 100 = 20%

S6. Ans.(b)
Sol. 4 + 4.44 + 0.4 + 44.04 + 444 = 496.88
