Question: If 2 < x < 4 and 3 < y < 7, what is the largest integer value of x + y?

  1. a.
    9
  2. b.
    10
  3. c.
    7
  4. d.
    8
  5. e.
    11
Answer: b
ব্যাখ্যাঃ If x and y are integers, the largest value of x + y = 3 + 6 = 9 However, note that although x + y has to be an integer, x and y does not need to be integers. So, largest possible value of x + y = 3.8 + 6.2 = 10 or x + y = 3.9 + 6.1 = 10 or x + y = 3.3 + 6.7 = 10 or x + y = 3.5 + 6.5 = 10 and the possible value of x and y whose sum is 10.
