Question

|- There are three times as many
girls as boys in a school. Find
an expression in terms of x,
for the total number of
Students in the school, where
x represents the number of
boys in the school.
​

Answer 1

the number of girls be x, then from the question, it is clear that number of boys are 3x,

Therefore, total no. of students = Number of boys + Number of girls = 3x+x=4x Now, the total number of children in the class must be a multiple of 4

(C) does not qualify this condition.

Therefore, 42 does not represent the total number of children in the class.

Answer 2

Step-by-step explanation:

Let the boys be 'x'...

therefore the number of girls will be '3x'

we know that the total number if students in a school is the addition of all the boys and girls .

Therefore AC

x + 3x = 4x...

implies that there are 4x students in the school where x represents the number of boys
