abcd*4=dcba what is the number abcd?

• abcd * 4 = dcba so for multiplying with 4 more than 2500 it exceeds 4 digit value.
  so it is less than 2500
  probability of getting values in a position is 0,2,4,6,8 but 0 we can't take because if we take 0 it becomes 3 digit value so 0 is eliminated remaining 2,4,6,8. values are less than 2500 so a=2
  so for answer 2 should come at the end such that the value is 12,32 are the only 2 options for it taking 12 means 3 at d position or taking 8 means d is 8......solve in this probability manner answer is..... 2178
