Answer:
33.33 days
Step-by-step explanation:
Let say A finish job in D days
a is twice as good a workman as B
=> B will finsh the same job in 2D days
A is able to finish a job in 50 days less than B
=> 2D - D = 50
=> D = 50
=> A finsh job in 50 days
& B finish job in 100 days
Together they will finish the job in 1/(1/100 + 1/50) = 100(1 + 2)
= 100/3
= 33.33 days
