Question

3 men can build a wall in 4 days than 4 men can build it in how many days​

Answer 1

Answer:

The answer is 3 days.

If 3 workers built the wall in 4 days it means each worker can build 1/12 wall per worker day

If X is the number of days for 4 workers

X*((1/12) wall/(worker*day))*4 worker = 1 wall

Worker and wall cancel out resulting in the following:

Worker and wall cancel out resulting in the following:(X/(12 day))*4 = 1

Worker and wall cancel out resulting in the following:(X/(12 day))*4 = 1X/(3 day) = 1

X = 3 days
