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

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.

If x and y are positive what is the value of x? [#permalink] New post   13 Aug 2020, 11:14
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

I agree on that point.
My doubt is if x=3.927y. So no matter what is the value of y the max rounded value of x=3.93.
The doubt I have is, is y a digit in x or is it being multiplied?

The question clearly defines if the variable represents a digit. Unless it's defined as digit, it is considered a multiplication of values.

For example check this question: https://gmatclub.com/forum/edited-for-a ... 53568.html
