Question

Yeah is twice as good as workman as b and together they finish a piece of work in 14 days in how many days can a alone finish

Answer 1

Let the B's ability to do work = X
Therefore, in one day B can do work = 1unit
Then the A's ability to do work = 2X
Therefore, in one day A can do work = 2 units
Altogether they complete the work = 14 days
X + 2X = 14
3X = 14
Total work done = 14 x 3 = 42 units

Now B can alone do work in = 42/1
= 42 days
A alone can compete the same
work in = 42/2 = 21 days.
