No. of students who participated in GK
In college A = 182
In college B = 200
In college C = 120
In college D = 130
In college E = 183
Total number of students of GK in all the colleges = 182 + 200 + 120 + 130 + 183 = 815
No. of students who participated in Science
In college A = 100
In college B = 100
In college C = 150
In college D = 200
In college E = 80
Total number of students in all colleges = 100 + 100 + 150 + 200 + 80 = 630
Increase in students in gk than science = 815 - 630 = 185
Percentage increase = 185/630 × 100 = 29.365 ≈ 29.37% [ correct upto two decimal places]
Hence the percentage increase is 29.37% .
