If the average (arithmetic mean) of a and b is 160, and c – a = 200, what is the average of b and c?  Choose the correct choice from the following
A) 260  B) 250  C) 150  D) 225  E) 325
a+b/2 = 160   =&gt; a+b = 320   a = c - 200...sub this value   c-200+b =320   =&gt;c+b = 520   =&gt;c+b/2 = 260   260nswer : 260
