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. Solution

Answer 1

Answer:

107 is greatest integer

Step-by-step explanation:

1. let set of four integers be x1,x2,x3,x4
2. given avg. of two small integers=102
3. i.e.x1+x2/2=102
4. x1+x2=204
5. also (x1+x2+x3)/3=103
6. 204+x3=309
7. x3=309-204
8. x3=105
9. also , (x1+x2+x3+x4)/4=104
10. 204+105+x4=416
11. x4=416-309
12. x4=107
13. so, x4 is greatest integer
