Riddle me this i'm thinking of a number it is odd is between 1 and 100 is higher than 20 it is smaller than the answer to 6 times 6 it is a multiple of 5 the sum of its digits is 7

- odd number between 20 and 36
36 - 20 = 16 / 2 = 8 possible numbers
21, 23, 25, 27, 29, 31, 33, 35

- multiple of 5
leaves only two of the above possibilities
25 or 35

- sum of digits = 7
2 + 5 = 7

The number must be 25
