Question

If a man a completes work in 15 days and other man in 12 days what time will both take to complete the work together

Answer 1

Answer:

(15+12)/4=6 days 7 hours 5 minutes

Step-by-step explanation:

if man A complete his work in 15 days and another man complete his work in 12 days,

then,

the time taken by both = 15+12=27.

the average time taken by one of them= 27/2

                                                                  =13.5 days

the total time taken by both = 13.5/2

                                              = 6.75 days.
