if you double each number, then the median will double as well

if you increase each number, then the median will increase as wellb) increasing each number by 10

the smallest number may overtake the median if you increase it too much, thus changing what number we take for the medianc) increasing the smallest number only

it might undertake the mediand) decreasing the largest number only

this is the only plausible answer by process of elimination. but you see how it makes sense, right?e) increasing the largest number only
