Question

In how many ways can 11 software engineers and 10 civil engineers be seated in a row so that they are positioned alternatively?

Answer 1

hi dear,
here is ur answer...........
...............................
..............................
The no. of ways in which they sit alternatively=11!*12*11*10*9*8*7*6*5*4*3 ways
this is because no of arrangements of software workers=11!
and then  by gap method we see that 12 seats will be there and on that seats 10 civil workers can sit by their choice
hope it helps uh........
