The average (arithmetic mean) of 4 different integers is 68. If the largest integer is 90, what is the least possible value of the smallest integer? Pick:
A) 5  B) 19  C) 29  D) 30  E) 33
Total of Integers=68*4= 
<gadget id="calculator">68*4</gadget>
<output>272</output>
272   Lowest of the least possible integer is when the middle 2 intergers are at the maximum or equal to the highest possible integer.   But all integers are distinct. So if the largest integer is 90, then the middle 2 will be 88 and 89   Lowest of least possible integer= 272-(90+89+88)=272-267=
