Hey guys, I'm prepping for the Dec SAT and I think a daily math questions would help me improve. Can anyone help me with these questions? If you nee help too, feel free to post.

1. Kyle's lock combination consists of 3 two-digit numbers. The combination satisfies the three conditions below.

-One number is odd
-One number is a multiple of 5
-One number is the day of the month of Kyle's birthday

If each number satisfies exactly one of the conditions, which of the following could be the combination of the lock?

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

I'm confused because A, B, and D all fit the conditions...
