Question

If it takes 2 nurses 2 minutes to measure the blood pressure of 2 patients, how long would it take 200 nurses to measure the blood pressure of 200 patients (in minutes)?

Answer 1

200 minutes because the 2 nurses take 2 minutes for the 2 patients. So it would make sense for 200 nurses to take 200 minutes for 200 patients.

Answer 2

it will take 2 minutes for 200 nurses to measure the blood pressure of 200 patients .

Explanation:

We know that the work-time and number of labor and efficiency formula is given by:

`Efficiency=(Number\ of\ labor* Time)/(Work\ done)`formula is given by:

Here Number of labor=Number of nurses.

Work=Number of patients whose blood pressure were noted.

As the efficiency will be same this means that:

`(2* 2)/(2)=(200* x)/(200)`

where x denotes the number of time taken by 200 nurses.

Hence,

`x=2`

Hence, the answer is:

2 minutes.
