If x > 5 and y < -1, then which of the following statements is true?
(x + 4y) > 1
x > -4y
-4x < 5y
None of these
Substitute x=6 and y=-6 ,
x+4y = -18
x = 6, -4y = 24
-4x = -24, 5y = -30
So none of the options out of a,b or c satisfies .

assume y = -2/-3/-4 then condition C (-4x < 5y) will suffice.
Hi Heemang, we need to find the statement that is true for all y < -1. Hence, if the statement fails for one value of y, the statement is not true.
Is the question asking which one will always be true? because if we put x=6 and y=-2 we are getting the third option to be true...???
yes,
it is asking for all the cases.
Hope this helps.
