sounder
w.o mathematical calculation also we can easily determines the ans
A & C = 4 DAYS MEANS BOTH OF THEM TAKES LESSER TIME THAN THE "B" becoz when B includes then time taken for work is too much
so its clear that B will take more time than A & C.

now look at this when B WORKS WITH A IT TAKES 72 DAYS
B WORKS WITH C IT TAKES 120 DAYS
B IS COMMON TO BOTH
IT MEANS WE CAN NEGLECT B's WORK
HENCE IT IS UNDERSTOOD THAT A WILL TAKE LESS TIME THAN OTHERS.
