There are 40Student in a class. If the number of boys is 4less than the number of girls. find the number of boys.

18

Step-by-step explanation:

Let number of girls be 'x'.

So, Number of boys = Number of girls - 4

= x - 4

Total number of students in a class = 40

Number of girls + Number of boys = Total number of students in a class

x + x - 4 = 40

2x - 4 = 40

2x - 4 + 4 = 40 + 4

2x = 44

x = 22

Number of boys = 22 - 4

= 18
