Question

The average (arithmetic mean) of 4 different integers is 75. If the largest integer is 90, what is the least possible value of the smallest integer? A 1 B19 C29 D30 E 33

Answer 1

well look at it this way... if the integers are different

the largest is 90

then the next largest could be 89 and the one before that 88

so

\[\frac{a + 88 + 89 + 90}{4} = 75\]

solve for a

Answer 2

33 that's right

Answer 3

well that would be my answer
