If the average (arithmetic mean) of x and y is 60, and z – x = 80, what is the average of y and z?
Choose the correct choice from the following choices.
A) 100	B) 120	C) 125	D) 115	E) 90
x+y/2 = 60   =&gt; x+y = 120   x = z - 80...sub this value   z-80+y = 120   =&gt;z+y = 200   =&gt;z+y/2 = 100   100nswer : 100
