Problem Statement

A list of integers has mode 32 32 and mean 22 22. The smallest number in the list is 10 10. The median m m of the list is a member of the list. If the list member m m were replaced by m \plus{} 10, the mean and median of the new list would be 24 24 and m \plus{} 10, respectively. If m m were instead replaced by m \minus{} 8, the median of the new list would be m \minus{} 4. What is m m? <spanclass=latexbold>(A)</span> 16<spanclass=latexbold>(B)</span> 17<spanclass=latexbold>(C)</span> 18<spanclass=latexbold>(D)</span> 19<spanclass=latexbold>(E)</span> 20 <span class='latex-bold'>(A)</span>\ 16\qquad <span class='latex-bold'>(B)</span>\ 17\qquad <span class='latex-bold'>(C)</span>\ 18\qquad <span class='latex-bold'>(D)</span>\ 19\qquad <span class='latex-bold'>(E)</span>\ 20
