If the arithmetic mean of x,y and z is 6 times the arithmetic mean of w, x and y. What is the value of the expression (x+y)?
Choose the most appropriate option.
A) (z-5w)/6	B) (z+6w)/5	C) (-z-5w)/6	D) (z-6w)/5	E) (z-6w)/6
Arithmetic Mean 1 = (x+y+z)/3   Arithmetic Mean 2 = (w+x+y)/3   Arithmetic Mean 1=6*Arithmetic Mean 2   (x+y+z)/3=6*(w+x+y)/3   x+y+z=6w+6x+6y   x+y=(z-6w)/5   Hence, the correct answer is (z-6w)/5
