If the successive tick marks shown on the number line above are equally spaced and if x and y are the numbers designating the end points of intervals as shown, what is the value of y?

x = 3 ticks.
y = 7 ticks.

(1) x = 1/2 --> x = 1/2 = 3 ticks --> 1 tick = 1/6, thus y = 7 ticks = 7/6. Sufficient.

(2) y - x = 2/3 --> the distance between x and y is 4 ticks, thus 2/3 = 4 ticks --> 1 tick = 1/6, thus y = 7 ticks = 7/6. Sufficient.

Let one interval = a. y = 7a, x = 3a. So we are only required to find a.

1) 3a = 1/2. a can be found. Sufficient

2) 7a - 3a = 2/3. 4a = 2/3. a can be found. Sufficient.

I have a question for this type of DS problem. If one is absolutely sure that statement 1 is sufficient, during a exam under time pressure, could we plug statement one's given variable into statement 2 to test out?

For example:

Statement 1) Given x=1/2
"I'm sure that it is possible to get y if we have 0 and X=1/2 on the number line. So sufficient."

Statement 2) Given y-x=2/3
"Since I'm confident that statement one is sufficient, let's try plugging in 1/2 for x."

so:
y-x=2/3

y-(1/2)=2/3 "From here I know that we can get y" Suf.

y=7/6

Is this reasoning okay?

Can we do this

For me this must be a bad idea during the exam, because in stress, minor mistakes are very common, so, for me, Such practices must be avoided.
