Question 178126
each even row's max will be value of the row divided by 2
each odd  row's max will be value of the row divided by 2 +1
:
there are 10 even rows and 10 odd rows.  
:
if you take the max of the 20th row which is odd plus the max of the 1st row which is even you will arrive at 20 which is the same as the number of rows we have.....hmmmmmmmmm!!!!....if you continue to pair in this manner, 19th row with the 2nd row ,18 with the 3rd each time you will arrive at 20 students max:
therefore the max value of students is
:
20(10)=200
:
kind of reminds me of Gauss's sum of a series equation
