Q:
A) 47/7 days | B) 59/6 days |
C) 48/5 days | D) 57/5 days |
Answer: C) 48/5 days
Explanation:
Explanation:
Amount of work K can do in 1 day = 1/16
Amount of work L can do in 1 day = 1/12
Amount of work K, L and M can together do in 1 day = 1/4
Amount of work M can do in 1 day = 1/4 - (1/16 + 1/12) = 3/16 – 1/12 = 5/48
=> Hence M can do the job on 48/5 days = 9 (3/5) days
