The average (arithmetic mean) of 4 positive integers is 50. If the average of 2 of these integers is 40, what is the greatest possible value that one of the other 2 integers can have?  Choose one:
A) 55
B) 65
C) 119
D) 109
E) 115

Rationale: "a + b + c + d = 200 a + b = 80 c + d = 120 greatest possible = 119 ( just less than 1 ) answer = c"
Answer: C
