(1) x = 3.927y
(2) y = 2.279


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
