If x and y are positive integers, Is 100x + y divisible by 9?
(1) x = 5
(2) y = 98
Maybe I am missing something or maybe you are missing something.
An expression is divisible by 9 when the sum of its digit is divisible by 9
if X is 1 then 100+98=198. exp. is div.by 9
if x=2 then 200+98 =298 exp. is NOT div.by 9
how is the answer B?
