Answer 1

Answer: 22 chefs can prepare meals for 737 people in 5 hours.

Explanation:

Given :

• 10 chefs prepare a meal for 536 people in 8 hrs.

• It is assumed that chefs cook at the same rate and that rate is constant throughout the preparation.

To Find : The number of people 22 chefs can prepare a meal for in 5 hours.

Explaination :

As given, they make a meal for 536 people in 8 hours which means 536 meals in 8 hours,

∴ meals per hour = 536/8

= 67 meals per hour

10 chefs prepare 67 meal per hour, then

meals per chef per hour = 67/10

= 6.7 meals per hour per chef

Now,

meals per 5 hours = 5 hours × meals per hour

= 5 × 6.7

= 33.5 meals per 5 hours

Each chef prepares 33.5 meals in 5 hours

then,

22 chefs make meals in 5 hours = 22 × 33.5

= 737 meals
