The sum of five numbers is 800. The average of the first two numbers is 100 and the third number is 150. Find the average of the two numbers?  Choose the most appropriate option
A) 225  B) 250  C) 240  D) 260  E) 270
Let the five numbers be P, Q, R, S and T.   =&gt; P + Q + R + S + T = 800   (P + Q)/2 = 100 and R = 150   P + Q = 200 and R = 150   P + Q + R = 350   S + T = 800 - (P + Q + R) = 450   225verage of the last two numbers   = (S + T)/2 = 225   225nswer:225
