If x = (1/2), is y equal to 1?
I] y^2 (2x + 1/2) = 1
II] y (2x - 1) = 2x - y
The OA is B, which was simple but I again made a silly mistake... I need a coffeee.....
Explanation:
statement 1: y^2 (x + 1/2) = 1
therefore, putting the value of x, we get
y^2 = 1
therefore, y = + or - 1
Hence insufficient...
Statement 2: y (2x - 1) = (2x - y)
putting the value of x, we get,
0 = 1 - y
therefore, y = 1.
hence sufficient.
I really do not know how the hell did I commit a mistake here...
I took the equation as y (2x - 1) = 2x - 1
therefore I got the answer as E....
