<h3>What is Margin gain ?</h3>
The gain of the desired effect with respect to the previous gain is called margin gain
The marginal gain from 8:00 am to 9:00 am is
(40-0) = 40 problems
The marginal gain from 9:00 am to 10:00 am is
= 70-40 = 30 problems
The marginal gain from 10:00 am to 11:00 am is
(90-70) = 20 problems
As if she does more than one hour of problem solving her productivity decreases to 30 which is less than 1 hour of reading textbook
