Question 368892
The number is a 5-digit number, with the middle digit being four.
By direct use of the information,
tens digit = 2*4 = 8
thousands digit = 4-3 = 1
ten-thousands digit  = 4+2 = 6.
Now the sum of the digits is 22.  If x= ones digit, then 
6+1+4+8+x = 22, or x = 3.  Therefore the number is 61,483.
