Recall the concept of Median . https://en.wikipedia.org/wiki/Median

As here 252 cans of soda sold to even no of customers i.e. to 100 customers , so median will be the average of the 50th and 51st largest amount of cans per person .

First they each have one can atleast one can . Now think for the rest 152 cans and 50th and 51st customers . Then in order to proceed divide 100 customers in two groups as first 49 customers and second 51 customers .

To minimize the first 49, they will be sold no more cans. Now 152 cans left to divide among next 51 customers . Taking \( \frac {152}{51} \) gives us 2 and a remainder of 50. Seeing this, the largest number of cans the 50th person could have is 3 ( including the can in 1st distribution), which leaves 4( including the can in 1st distribution) to the rest of the people. The average of 3 and 4 is 3.5 . So the maximum possible median is 3.5 .
