: A can do a work in 8 days and B in 12 days.
How long will A and B take to do the same work together?
:
Let t = time required when working together
Let the completed job = 1
:
t%2F8 + t%2F12 = 1
multiply by 24 to clear the denominator, results:
3t + 2t = 24
t = 24%2F5
t = 4.8 days working together
