A and B can do a work in 18 day, B and C in 30 days, A and C in 22 (1/2) days. In how many days can A,B and C individually do the work?

Answer»

None of these



(A+B+C)'s two days work = 1/18 + 1/30 + 2/45

= (5 + 3 + 4)/90 = 2/15

(A+B+C)'s one DAY work = 2/15 * 1/2 = 1/15

A's one day's work = 1/15 - 1/30 = 1/30

B's one day's work = 1/15 - 2/45 = 1/45

C's one day's work = 1/15 - 1/18= 1/90

So, A,B and C can individually do the work in 30, 45 and 90 days.
