The arithmetic mean of 5 negative integers is -100. If the average of 3 of these integers is -90, what is the least possible value that one of the other 2 integers can have? Choose the correct choice
A) 229	B) - 1	C) - 229	D) 90	E) - 90

Rationale: the arithmetic mean of 5 negative integers is ( a + b + c + d + e ) / 5 = - 100 so , the sum of 5 negative integers would be a + b + c + d + e = - 100 * 5 = - 500 similarly , the sum of 3 negative integers would be a + b + c = - 90 * 3 = - 270 thus , the sum of the other 2 integers is - 500 + 270 = - 230 . since we know that the integers are negative then the least one from these two can be - 229 , the other one being - 1 . hence , the correct ans is c
Answer: C
