SOLUTION:

Sol Q1
Percentage of passed candidates from Class VI = 81.78%
Percentage of passed candidates from Class VII = 82.54%
Percentage of passed candidates from Class VIII = 86.04%
Percentage of passed candidates from Class IX = 88.27%
Percentage of passed candidates from Class X = 91.23%


Sol Q2
Required Ratio
(56+40+38+40+88):(8+8+8+12+2)
262:38
131:19

Sol Q3
Percentage of candidates passed of Class IX
in 2005 = (54x100)/64 = 84.375
in 2006 = (51x100)/56 = 91.07
in 2007 = (63x100)/74 = 85.13
in 2008 = (66x100)/69 = 95.65
in 2009 = (78x100)/88 = 88.63
in 2010 = (40x100)/52 = 76.92
in 2011 = (62x100)/66 = 93.93

Sol Q4
Required Average = (8+14+14+15+14+8+4) / 7 = 77/7 = 11

Sol Q5
Total number of students appeared for the
Class VII = 72+66+64+53+58+48+80 = 441
Class IX = 64+56+74+69+88+52+66 = 469
Class X = 65+60+74+80+88+90+68 = 525

Required Total = 441+469+525 = 1435
