Answer 2

Answer:

Step-by-step explanation:

Hi friend

Here is the answer for your question

Here 4 men can make 4 cupboards in 4 days.

4 men can make 1 cupboard in 1 day.

1 men can make 1/4 cupboard in 1 day.

so 14 men can make in 1 day is 14* 1/4 cupboard.

and 14 men can make in 14 days is 7*7 cupboards.

Thus, 14 men can make 49 cup boards in 14 days.

4:14 members = 4:14 days = 4: x cupboards.

Here days are directly proportional to cupboards made.

and Number of members are indirectly proportional.

So inverse ratio of 4:14 is 14:4

14:4= 4:14/4:x

14/4= 4/14*x/4

14/4=x/14

196/4 = x

x =49 Cup boards.

So 14 men can do 49 cupboards in 14 days.

Hope this helps you.
