If 65% of the total-number of students selected from college IIT Guwahati are boys and they form 40% of the total number of boys in the college, then what percentage of the girls in the college got selected through campus placements?
» Explain it
A
Following common explanation we get ;

Number of boys selected =  65  × 80 = 52
100

The number of boys = 52 ×  100  = 130
40

The number of girls = 240 – 130 = 110
Required percentage =  28  × 100 = 25.2%
110
