Equation: 2x – 4y = 13

(1) x is a positive integer. Not enough information. Insufficient.

(2) 5y = 3x; One can substitute y with x in the equation and can get x. Sufficient.

Answer B.

y=(3*x)/5
=> 2x-4*(3*x)/5=13
=> 10x-12x=65
=> -2x=65
=> x=-65/2

Hence, B is correct.

(1) x is a positive integer
(2) 5y = 3x



Sorry Bunuel,

But here both the statements seem to contradict each other . According to statement 1, X should be a positive integer.
However statement 2 , seems to say something different.

X should be a positive integer according to both the statements .

Please correct me , if I am missing anything.
