Thank you very much sir for the quick reply. now I understand. However, the way the solution is done is still different between the two questions of Q98 and Q103.

Q 98 just simply picked the highest number among the figures of each choice on the regret table, while Question 103 added all the figures of each choice on regret table, and the final figure they chose was the one minimises the maximum regret, if it had been done the same way as you or question 98, the figures used for minimax regret should have been “675000 for supply 350,000”, “360000 for supply 280000”, “750000 for supply 200000”, instead of the figure of 990, 710, 1150..??

either way it gives the same answer in this case, however, if it was not a multiple choice question, I would have got the figures completely wrong.

so should I stick to what I know or should I learn the rule used on question 103?

Hope to hearing from you sir.
