What is the value of |y − 1| ?
(1) (y − 7)(y + 5) = 0 --> y = 7 or y = -5, in either case |y − 1| = 6. Sufficient.
(2) 2y + 10 = 0 --> y = -5 --> |y − 1| = 6. Sufficient.
Answer: D.

What is the value of |y − 1| ?
(1) (y − 7)(y + 5) = 0
(2) 2y + 10 = 0
(1) (y − 7)(y + 5) = 0
(2) 2y + 10 = 0
(1) (y − 7)(y + 5) = 0
y=7 or y= -5
Putting these values of y in |y − 1|, we get 6 as the answer. Hence sufficient
(2) 2y + 10 = 0
y+5=0
y=-5
We get the answer by putting y= -5. Hence, sufficient.
D is the answer
