An odd number is a 2-digit multiple of 5. The sum of all its factors is 48. What is the number?

If it is a multiple of 5, it must be 0 or 5, then the two digit number will not be too large, because if the number is large, the factor will not be in the range of 48. The factor contains 1 and itself, so it can not exceed 48. Then there are 10, 15, 20, 25, 30, 35 and 40. The experiment shows that the two digit number is 35
