I wish to have this solution specially from
Ron Purewal....................
If y is an odd integer and the product of x and y equals 222, what is the value of x?
(1) x is a prime number.
(2) y is a 3 digit number.
My Solution:Is it wrong?
Correct Answer "D"...From the question we can have x=222/y where y is odd......From statement (1): x is prime. if I put the value of y=111 then x=2 which is prime and if I put ANY VALUE of y(without 111) x CAN'T BE PRIME). So statement (1) is SUFFICIENT.............. From statement (2): y is a 3 digit number, that means if I put the value of y from 100 to 999(which are odd) then I'll get many more values of x but I can't accept these values without 2 because, in QUESTION it is said that the product of x and y MUST BE=222(EVEN) AND Y IS ODD NUMBER. I know that(EVEN multiply ODD=EVEN) THAT MEANS,though x has no DIRECT restriction in STATEMENT 2 but x MUST BE EVEN. So, statement 2 definitely SUFFICIENT....SO RECAP THE ANSWER IS ''D"......thanks to all.
