Answer:
88,872
Step-by-step explanation
Let the 5 digit number be a b c d e.
Each of b,c,d,e are between 0 and 9. a is between 1 and 9.
Given
d = 7. (I solved this question without using this data given).
d - e = 5 ... So e is 0,1,2,3 or 4. d = 5,6,7,8, or 9.
c = e * 4 .... So e can be 0, 1, or 2 at most. c is 0 , 4 or 8.
b = c
a + b + c + d + e = 33
a + 4 e + 4 * e + (e+5) + e = 33
a + 10 e + 5 = 33
a + 10 e = 28
Since a is between 1 and 9, e has to be 2 only.
a = 8 and e = 2.
So c = 8 = b, d = 7.
Number is 88, 872
