Answer:
107
Step-by-step explanation:
The average of 4 integers is 104, hence sum of the 4 number is=416
Average of 3 integer is 103, hence sum of first 3 number=309
Hence, the 4th number is=416-309=107
Average of 2 numbers is 102, sum of 2 number =204
The 3rd number is =309-204=105
Other 2 numbers are obviously smaller as average is 102, hence greatest number is 107
