Question

A can do a job in 4 days, and B in 9 days.

(i) How long will they take to complete the job together?
(ii) If they are paid 900 for the job, what will be each person's share?

Answer 1

(i) (x/4) + (x/9) = 1

9x + 4x = 36

13x = 36

x = 2 10/13 days = about 2.77 days

(ii) A's share: $900(9/13) = $623.08

B's share: $900(4/13) = $276.92
