Answer:

a) 952

b) 136

Step-by-step explanation:

Ratio of b:g = 3:4, based on this we have:

Number of boys = 3x
Number of girls = 4x
Total number of pupils = 3x+4x = 7x

Number of spectacle wearers:

1/3*3x + 3/8*4x = x + 3/2x = 2.5x

Number of those not wearing spectacles:

7x - 2.5x= 4.5x

And this number equals to 612, then we can find the value of x:

4.5 x = 612
x= 612/4.5
x= 136

a) Total number of pupils:

7x = 7*136 = 952

b) The difference in the number of boys and girls:

4x-3x= x = 136
