Answer & Explanation 1. 5 2. 60% of (86.4/360 * 40000) = 60/100 * 9600 3. 2 4. 2 5. 5
50% of (64.8/360 * 30000)
= 50/100 * 5400 = 2700
= 5760
Total = 30000/(360 * 100) [54 * 40 + 90 * 55 + 64.8 * 50 + 50.4 * 60 + 43.2 * 45 + 57.6 * 60]
30000/(360 * 100) [2160 + 4950 + 3240 + 1944 + 3456]
30000/36000 * 18774 = 15645
Total boys = 4000 + 4800 + 1800 + 1600 + 2880 + 5760 = 20840
Total girls = 40000 – 20840 = 19160
Diff = 20840 – 19160 = 1680
E-Boys2012 = 43.2/360 * 30000 * 55/100 = 1980
C-Boys2013 = 36/360 * 40000 * 45/100 =1800
Req% = 1980 * 100/1800 = 110%
