Dear quantskillsgmat, posting one question only once is sufficient.

I do not have any idea about any short method. Still i can solve it by preparing the magic square itself.


52 38 39 49
41 47 46 44
45 43 42 48
40 50 51 37


this is the magic square for the problem with range 37...52.

Please refer this link (https://www.mrexcel.com/tip069.shtml)to know how to prepare it in fraction of secs.
