1) Insufficient
Let Y =0.x2 where x is some digit.
Z = 0.14
In this case we dont know the tenth digit of X. Hence insufficient

2) Insufficient
Let Y = 0.312. This does not tell us anything about Z

1) + 2) Sufficient The answer is YES

Let Y = 0.524
Z = 0.13x

Hence C

To find the answer it is imp to know the the relation between tenths digit of Y & Z.
from both statement together we can get it.
Hence =>C

a Y = 0.55 | 0.37 Z = 0.46 gives different results. Not sufficient.

b only Y and no X, no sufficient.

a+b Y = 0.645 | 0.325 X = 0.36 | 0.13 both the cases Y> X.

C

(1)

y= 0.25
z = 0.46

y = 0.25
z = 0.16

Insufficient

(2)
tenths digit of Y is greater than hunderd's digit
Insufficient as we don't know about z

(1) + (2)

Tenths digit of y is > tenths digit of z

So y > z

Y = .abc

Z = .pqr

from statement 2: a > c > b

From statement 1:
b>P

from statement 1 a > b so a > p

there for Y is > Z

+1 for C.

Let Y = 0.cde
Let Z = 0.rst

Statement I: d > r ; d < s : Insufficient as we need relationship between c and r.
Statement II: e> d;e < c : Insufficient as we need relationship between c and r.

I and II together : c > e > d > r => Y > Z. Hence C
