numbers starting with 5: 51,53 and 55 only three numbers are allowed.
numbers starting with 10, 11, 12, 13, 14 and 15 each will contribute three more numbers.
total odd numbers between 100-199 = 6*3 = 18
similarly,
total odd numbers between 200-299 = 6*3 = 18
total odd numbers between 300-399 = 6*3 = 18
total odd numbers between 400-450 = 5*3 = 15; only numbers starting with 40,41,42,43 and 44 will contribute three numbers each.
total odd numbers between 50 - 450 = 3+ 18*3 + 15 = 72
