Answer & Explanation 1. (3) 2. (1) 3. (5) 4. (3) 5. (2)
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
Total number of girls passed in 2009 = 288
Total number of boys failed in 2009 = 770 – 512 = 258
Total sum = 288 + 258 = 546
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
Required Ratio = 770 : 330 = 7:3
Number of boys passed in 2005 = 480
Number of girls appeared in 2006 = 400
Req % = (480 – 400)/400 * 100 = 20%
