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 ?
Pick:  A) more than 7  B) Less than 3  C) More than 3  D) Less than 1/3  E) none of these
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] &gt; 7   more than 7NSWER:more than 7
