average of 5 non negative integers is 9. If sum of any 3 integers out of 5 is 36, then the possible product of other 2 will be

OPtion

1) 10
2) 28
3) 14
4) 8
5) 30
6) 12
7) 9
8) 15
9) 21
10) none of these

Solution

non negative means 0 is also a possible integer.
now grand sum of 5 integers = 45
sum of 3 integers = 36
so sum of other 2 = 9
possible cases are
0,9
1,8
2,7
3,6
4,5
now check
