Question

In a set of four integers, the average of the two smallest integers is 102, the average of the three smallest integers is 103, the average of all four is 104. Which is the greatest of these integers?​

Answer 1

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
