Answer 1

40% are boys and their number is 18=18×100/40=there are 45 students in the class

Answer 2

Answer:

Let the total number of students in the class be x

Since girls are the the 60% of total students of class , then boys are the 40% of total students

ATQ

$x \times \frac{40}{100 } = 18$

$x = \frac{18 \times 100}{40}$

$x = 45$

Hence total number of students in class = 45
