Answer 1

Given that 12 men and 15 women can do a work in 24 days.

Then 1 men can do 1/288th of the work in 1 -day.

Then 1-women can do 1/360th of the work in 1-day.

Now,

8 Men + 8 Women = 8(1/288) + 8(1/360)

                                = 8/288 + 8/360

                                = 1/36 + 1/45

                              LCM = 180

                                = (1 * 5 + 1 * 4)/180

                                = 9/180

                                = 1/20 of the work in 1-day.


Therefore the number of days taken to complete the work = 20.


Hope this helps!
