Answer:

14 is the correct answers

Answer 2

Therefore in 25 days B will finish the work .

Step-by-step explanation:

Given that A alone can do a piece of work in 35 days.

Let total work = 100 units.

B is 40% more efficient than A.

It means B can do 140 units in 35 days.

B can do 1 unit in $\frac{35}{140}$ days

B can do 100 unit in $\frac{35\times 100}{140}$ days

                               = 25 days

Therefore B will finish the work in 25 days.
