10 men can complete a piece of work in 15 days and 15 women can complete the same work in 12 days. If all the 10 men and 15 women work together, in how many days will the work get completed?

• 6 days and 16 hours.
  In 1 day, 10 men can do 1/15 of the work and 15 women can do 1/12 of the work, so in 1 day working together they would do 1/15 + 1/12 of the work i.e. 3/20 of the work.
  So it would take 6 days and two-thirds of 7th day.

• (2*15*12)/(12+15) = 20/3 = 6 2/3

• 10->[1/15]
  15->[1/12]
  10+15=1/15+1/12
  =3/20
  so answer is=20/3=6+2/3
