Note : All spaces are equal , let each space be denoted by S then:
Statement 2 : 4S=2 then S = \(\frac{1}{2}\) so each space is \(\frac{1}{2}\) if y = 2 then x= 1.5-> Not Suff.
Statement 1 : We do not know the value of x or y hence we cannot find x -> Suff.
Ans- B
Hope it's clear.

Don't you think the correct should be C.....Please let mw know if my solution is correct.....
since x and y are designating the endpoints of the intervals, this means that y-x = 7s
s refers to the spaces
statement I
x=3y/4
from above we know that y-x = 7s
if we put the value of x in the formula y-x = 7s
we get s=y/28
Not sufficient as we don't know the value of y
statement II
y=2
from stem we know that y-x = 7s
if we put y in the formula we get x = 2-7s
still NS
Statement I and II together
from I we have x = 3y/4
from II we have y =2
if we put y = 2 in x=3y/4 we get x =1.5
hence both the statements together are sufficient
correct option should be C
Please let me know the detailed solution if I have done something wrong.
