Answer & Explanation

6.d;
Total number of passed students of College A =(100*220)/55   = 400
Number of girls passed = 45% of 400 = 180
Total number of passed students of College= (100*175)70  = 250
Number of girls passed = 30% of 250 = 75
Difference = 180 – 72 = 105
7.d;
For College A,
35% of girls = 70
Total student =(70*100)/35   = 200
For College B,
40% of girls = 70
Total student =  (70*100)/40 = 175
Sum = 200 + 175 = 375
8.a;
Total students passed of College A in 2004 = 175
Total students passed of College B in 2002 = 150
Difference = 175 – 150 = 25
9.c;
Number of girls passed of College= (44*400)/100  =176 Number of girls passed of College B =(36*500)/100 = 180
% difference =  [(180-176)/180]*100=20/9
10.d;
Number of girls passed from College A = Number of boys passed from College A = 200
Number of girls passed from College B = 48% = 240
Total passed=(240/200)*48=500
Number of boys passed=52% of 500 = 260
%=(260/200)*100=130%
