Let number of boys = x
Let number of girls = y
Therefore x/y = B and y/x = G
3(B + G) = 3[(x/y) + (y/x)] = 3[(x2 + y2)/xy] > 3
If the ratio of boys to girls in a class is B and the ratio of girls to boys is G; then 3 (B + G) is ?
Options:
- Equal to 3
- Less than 3
- More than 3
- Less than 1/3
- none of these
