Answer 1

Step-by-step explanation:

The ratio of boys to girls is 4 : 7

Let, the number of boys is 4x

so, the number of girls is 7x

total students = 4x+7x = 11x

11x = a number between {24, 30}

but there is no natural number between 24 and 30 which is divisible by 11

so, the range{24, 30} is not correct
