Question

Answer 1

Answer:

% of girls = 30

Number of girls = 18

so , 30 % of a number is 18

Let the number be X

then , 30/100*x=18

So , By evaluating , we get the answer as 60.

60= total number of students .

Number of boys = total number of students - total number of girls

= 60 - 18

= 42

Number of boys = 42
