The percentage of the boys studying in Management discipline comparing to the total number of students studying in that discipline is
Solution
Total number of students in the college = 5000
Number of students in Management discipline = $$\frac{10}{100}\times5000=500$$
Total number of girls = 2000
% of girls in Management discipline = 8%
=> Number of girls studying in Management discipline = $$\frac{8}{100}\times2000=160$$
=> Number of boys studying in Management discipline = $$500-160=340$$
$$\therefore$$ Require % = $$\frac{340}{500}\times100$$
= $$\frac{340}{5}=68\%$$
=> Ans - (D)
