Given :

Male student : female student : teachers = 3:2:1

Total number of people = 252

Let common factor of ratios be x

Then, 3x + 2x + x = 252

6x = 252

x = 252/6

x = 126/3

Now, male students = 3x

So, Number of male students = 126/3 × 3

= 126

Number of male(in%) = 126/252 × 100%

= 50%

Thus, number of males is 50%.
