3 days that my answer i hope you days good

Answer 2

Given: 14 men and 28 women working together

To find: Days in which the work can be done

Solution:

We will begin with finding out the one day's work

One day work of 14 men= 1/14

One day work of 28 women= 1/28

Therefore, the total work done by both = 1/4 + 1/28  

                                                                  LCM for the is 28                                    

                                                                   = 7+1/28

                                                                    = 8/28

                                                                    = 2/7

Now we reciprocate the fraction= 7/2= 3.5( round off the answer) = 4 days

The total number of days in which the work can be done in 4 days that is option (c).
