Question

3 chefs take 120 min to cook food for a definite number of guests. if the food is to be cooked in 90 minutes how many more chefs are needed ​

Answer 1

Given:

3 chefs take 120 min to cook food for a definite number of guests.

To find:

The number of chef required to cook the same food in 90 minutes.

Solution:

Let the number of chef is M

As per the given condition of the question, the total work done by the chefs would be the same in both cases.

So the total work done by the 3 chefs is given by:

• 3×120
• 360 units

and the number of chefs required to complete the same work in 90 minutes is given by:

• 360 = M×90
• M = 360/90
• M = 4

Hence four chefs can complete the same work in 90 minutes.
