Answer 2

Therefore Q alone completes the same work in 42 days.

Given:

P is twice good as Q. (  P = 2Q )

P and Q together can complete the work in 14 days.

To Find:

The number of days taken by Q to finish the same work =?

Solution:

This numerical can be solved using this simple assumption method.

Let us assume the total work to be finished = 14 × 3 = 42 units

Then the work done by P and Q in one day = 42 / 14 = 3 units

In one day ⇒ P + Q = 3 units

⇒ 2Q + Q = 3 units

⇒ 3Q = 3 units

⇒ Q = 1 units then P = 2Q = 2 × 1 = 2 units

So Q alone can do 1 unit of work in one day

Then to complete the total work of 42 units Q takes 42 / 1 = 42 days

Therefore Q alone completes the same work in 42 days.
