Question: If x and y are positive what is the value of x?
Statement 1: x = 3.927y
x is dependent on y and y is unknown hence
NOT SUFFICIENT
Statement 2: y = 2.279
relationship between x and y is unknown to use value of y to calculat evalue of x hence
NOT SUFFICIENT
Combining two statements
x = 3.927y and y = 2.279
i.e. x = 2.927*2.279
SUFFICIENT
Answer: Option C

How do we know whether y is multiplies or a digit of x?
If y is a digit statement 1 is sufficient.
If y is multiplied than C is the right answer.

Statement 1: x = 3.927y
the question does not give info about y, so y could be 1 or 2, etc, giving different values of x
NOT SUFFICIENT
Statement 2: y = 2.279
y is giving but nothing on x
NOT SUFFICIENT
Combining two statements
x = 3.927 * y, where y = 2.279
x = 3.927*2.279, which gives an unique value
SUFFICIENT
