  1. y is divisible by 3

  2. y is divisible by 6

  3. y is divisible by 9

  4. x + y is divisible by 9

D Correct answer
Explanation

LCM(x,y) = 36, HCF(x,y) = 4. x*y = LCM*HCF = 144. If x=4, then y=36. Check: x+y = 4+36 = 40. 40 is not divisible by 9. Thus, D is the statement that is not true.
