<p>Kyle's lock combination consists of 3 two-digit numbers. The combination satisfies the three conditions below.
1.one number is odd
2.one number is a multiple of 5.
3.One number is the day of the month of Kyle's birthday.</p>

<p>If each number satisfies exactly one of the conditions, which of the following could be the combination to the lock?</p>

<p>A.14-20-13
B.14-25-13
C.15-18-16
D.20-15-20
E.34-30-21</p>

<p>Answer: A</p>

<p>How come B doesn't work?</p>

<p>i think it's because for B, 2 numbers satisfy the first condition, and im pretty sure those conditions mean one number, and ONLY one number.</p>
