If the sum of the digits of the positive two-digit number x is 4, what is the value of x?

(1) x is odd.

(2) Twice the value of x is less than 44.

I disagree with OA..

x = ab = 10a+b

a+b = 4

x = either 13 or 22 or 31 or 40.

1: x is odd and could be 13 or 31.

2: 2x < 44.

x < 22.

x is 13. suff..

B.
