Question

there are between 24 and 40 students in a class.the ratio of boys to girls is 4:7. how many children in the class?

Answer 1

we know that the ratio between the no. of boys and girls is 4:7.

so 4x+7x will be the total no. of students.

which implies that 11x is the total no. of students.

As per question 11x is between 24 and 40

the only whole no multiple 11 between 24 and 40 is 33 .Hence the total no.of students is 33.

Answer 2

Answer:

there is 33 students in the class
