]Okay but if the ques was suppose "ratio of number of 5 diff dgit codes that can be formed to the 4 digit codes that can be formed"
then ans would be 6:1. right? so how are these 2 ques different? arent they the same concept?
If the digits must be different the answer would be 10C5/10104. If the digits can repreat the asnwer would be 10^5/10^4.
