(1) x is 4 more than twice y.

(2) The ratio of 0.5x to 2y is 3:5.


Question: x:y = ?

Statement 1: x = 4+2y
i.e. x/y = (4/y) + 2

We using this information x/y can't be calculated cause y is unknown hence

NOT SUFFICIENT

Statement 2: The ratio of 0.5x to 2y is 3:5

i.e. 0.5x / 2y = 3/5

i.e. x/4y = 3/5
i.e. x/y = 12/5

SUFFICIENT

Answer: Option B
