If the ratio of boys to girls in a class is B and the ratio of girls to boys is G; then 5 (B + G) is ?  Options:	A) Equal to 3	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   5(B + G) = 5[(x/y) + (y/x)] = 5[(x2 + y2)/xy] &gt; 5   ANSWnone of theseR:none of these
