take the lcm of days (10,20)= 20 units
lcm will be the total units.
so, a does work in 10 days= 2 units /day
and, b does work in 20 days= 1 units/ day
Therefore, total units done by a and b together= 3 units/day
No. of days work by a and b together= total units/ total units produced by a and b together
no. of days= 20/3 = 6.666.. days or simply we can say 6.67 days
