I started my thinking process by finding the smallest multiple of 2, 4, 5, and 10. See the above linked post for the rest of my answer. 
20 divided by 6 = 3 with a remainder of 2.

my mystery number has 3 tens and 15 ones. What number am I thinking of?

it is less than 50 it is a square number the sum of the digits is 13
