Answer:
Given :-
60% of students are boys
Total girls = 460
Have to Find :-
Number of boys
Solution :-
At first
Percentage of girls = 100 - 60 = 40%
Therefore,
Let the number of total students be x
40/100 × x = 360
4/10 × x = 360
2/5 × x = 360
360 × 5/2 = x
1800/2 = x
900 = x
No. of students = 900
Number of boys = Percentage of boys/100 × Total students
No. of boys = 60/100 × 900
No. of boys = 6/10 × 900
No. of boys = 6 × 90
No. of boys = 540
