SOLUTIONS
(1) Average = (116 + 208 + 169 + 142 + 155 ) / 5
= 158
(2) Total admitted student till 2010 = 148 + 172 + 188 = 508
Total number of students who left till 2010 = 60 + 96 = 156
Difference = 352
Number of girls = 6/11 * 352 = 192
(3) College 1 = 161 + 148 - 58 = 251
College 2 = 148 + 172 - 60 = 260
College 3 = 179 + 161 - 90 = 250
College 4 = 116 + 208 - 60 = 264
College 5 = 128 + 191 - 50 = 269
(4) (116 + 148 + 135 + 112 ) - (58 + 69 + 88 ) = 341
(5) Students of College 5 at the end of 2009 = 128 + 191 - 50 = 269
Students of College 3 at the end of 2009 = 179 +161 - 90 = 250
Percentage = (269-250) / 250 * 100 = 38/5
(6) Ratio = (143 + 165 ) : (79 + 82 + 91 )
11 : 9
