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

\(Y\) and \(Z\) are both positive numbers less than \(1\). Is \(Y > Z\) ?

(1) The hundredths digit of \(Y\) is greater than the tenths digit of \(Z\) and less than the hundredths digit of \(Z\).

(2) The thousandths digit of \(Y\) is greater than the hundredths digit of \(Y\) and less than the tenths digit of \(Y\).
