If x and y are positive integers such that (x + y) < 10, then which of the following must be true?
A) x < 8
B) x > 3
C) x >y
D) x + y = 5
E) x - y <= 7
Let x = 8 & y = 1 or x = 1 & y = 1................. (Both positive Integers)
A) x could be 8...........
Eliminate B) x could be 1...........
Eliminate C) x could equal y........
Eliminate D) From examples, it is not a must tha both equalt to 5......
Eliminate E) No need to check but for practice take the maximum integers possible when x = 8 & y = 1 or vice versa..It is always true
Answer: E
