Answer: A = 3
Explanation:
The digit is 3. If A is 3, the number
2A5A0A2 becomes 2353032. We then divide by 99 and this will be:
= 2353032/99
= 23768
If we use 1, we'll have 2151012. Dividing by 99 gives:
= 2151012 / 99
= 21727.39
If we use 2, we'll have 2252022. Dividing by 99 gives:
= 2252022 / 99
= 22747.69
If we use 4, we will have 2454042. Dividing by 99 gives:
= 2454042 / 99
= 24788.30
If we use 5, we will have 2555052. Dividing by 99 gives:
= 2555052 / 99
= 25808.61
If we use 6, we will have 2656062. Dividing by 99 gives:
= 2656062 / 99
= 26828.91
If we use 7, we will have 2757072. Dividing by 99 gives:
= 2757072 / 99
= 27849.21
If we use 8, we will have 2858082. Dividing by 99 gives:
= 2858082 / 99
= 28869.52
If we use 9, we will have 2959092. Dividing by 99 gives:
= 2959092 / 99
= 29889.82
If we use 0, we will have 2050002. Dividing by 99 gives:
= 2050002 / 99
= 20707.09
Therefore, A is 3 as it gives 2353032 which divides 99 successfully without remainder.
