Answer 1

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
