Let number of boys = x
Let number of girls = y
Therefore x/y = B and y/x = G
7(B + G) = 7[(x/y) + (y/x)] = 7[(x2 + y2)/xy] > 7
If the ratio of boys to girls in a class is B and the ratio of girls to boys is G; then 7 (B + G) is ?
A: more than 7
B: Less than 3
C: More than 3
D: Less than 1/3
E: none of these
