BOOKMARKED
If y = O.abcd, where a, b, c, and d each represent a nonzero digit of y, what is the value of y?

(1) $$a = d^2$$ and $$b = c^2$$
The possible combinations are 9,3 or 4,2 or 1,1. Assign these in different order and y changes.
Not sufficient

(2) a > b
Clearly not sufficient

1+2)Given that a>b, b could be 1 or 4 and a could be 4 or 9 respectively. Still not sufficient
E

Similar question to practice:
Quote:
If y = 0.jkmn, where j, k, m, and n each represent a nonzero digit of y, what is the value of y ?

(1) j < k < m < n
(2) j + a = k, k + a = m, and m + a = n, where j > a > 1.

Great Question.
Here y=0.abcd
to get y we need to get a,b,c,d
Statement 1
using test cases
y=0.1111
y=0.4422
Hence not sufficient
Statement 2
y=0.3188
y=3189
Hence not sufficient
Combining the two statements
y=0.9113
y=0.9423
Hence not sufficient

Hence E
