i am a number greater than 40,000 and less than 60,000 my ones digit and tens digits are the same. my ten thousands digit is 1 less tha 3 times the sum of my ones digit and tens digit my thousands digit is half my hundred digit, and the sum of those two digit is 9

Lets let the one digit/ ten digit = "a"
Ten thousand digit must be 4 or 5 (between 40001 and 59999)
Ten thousand digit = 3(a+a) 1
= 3(2a) 1
= 6a1
Try 4
4= 6a 1
5 = 6a
5/6 = a
a= not an integer
Try 5
5= 6a1
6=6a
a=1
Thousand digit = Hundreds digit / 2
Thousand digit + Hundreds digit = 9
Thousand digit = 3
Hundreds digit = 6
Answer = 53611 
yeah........ answer= 53611
