Step-by-step explanation:

refer the above attachment

Answer 2

Girls = 120

Boys = 57

Girls left = 5% of 120 = 5/100 x 120 = 600/100 = 6

Girls remaining = 120 - 6 = 114

Total students now left = 114 + 57 = 171

% of boys of total students = 5700/171 = 33 1/3 = 33.33% 57/171 * 100

Boys is 33.33% of total students.
