Q:1 i have made same matrices but don't have any hint to solve the problem. I'll make my own calculations but give some idea.
Q:2 This is not because excel returns an error but also the given matrix is not a square matrix and inverse of matrix other than a square matrix is not possible.
salam dear
question no 1
is not a matrix question . i think its a ratio question
to fillfull the reservation company has to fly
boeing 757 3 planes
boeing 767 1 planes
boeing 777 2 planes

As in
boieng 757 767 777
Tourist 50 75 40 and reservation for tourist is 305
50*3 75*1 40*2
150 75 40 = 150+75+80 =305

as in
boieng 757 767 777
economy 30 45 25 and reservation is 185 for economy
30*3 45*1 25*2
90 45 50 = 90+45+50=185
and third is same
