If w/x = 2/3 and w/y = 6/15, then (x + y)/y =	Choose the correct choice from the following:	A) 4 / 5	B) 6 / 5	C) 7 / 5	D) 8 / 5	E) 9 / 5

Rationale: w / x = 2 / 3 = > x = 3 / 2 w and w / y = 6 / 15 = > y = 15 / 6 w ( x + y ) / y = ( 3 / 2 w + 15 / 6 w ) / 15 / 6 w = 4 w / ( 15 / 6 w ) = 8 / 5 correct option : d
Answer: D
