Question

Mr Dlomo's class has a ratio of 2 boys to 3 girls. Mrs Tshabalala's class has a ratio of 1 girl to 2 boys. Both classes have 30 Learners. Calculate the total number of boys in the two classes
​

Answer 1

Answer:

Let us consider 2x as of boys.

and Let us consider 3x as number of girls.

So, 2x+3x=30

5x=30

So, x=6

So,

As 2x is boys, 2*6=12

And in Tshabla's class,

Let x be number of girls

Let 2x be number of boys

So, 1x+2x=30

x=10

So, 2*10=20

So, total number of boys in both classes is 20+12=32
