Question

a person can complete a work in3 days, another person can complete it in 4 days how many days will they take to complete the work

Answer 1

Answer:

12/7 days.

Step-by-step explanation:

Amount of work done by the 1st person in 1 day = 1/3

Amount of work done by the 2nd person in day = 1/4

Amount of work done by both in 1 day = 1/3 + 1/4 = 4/12 + 3/12 = 7/12

So, both will complete the work in 12/7 days.
