Answer 2

Given:

• 10 chefs prepare a meal for 536 people in 8hours.
• assuming that chefs cook at the same rate and that rate is constant throughout the preparation.

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

explanation:

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

                ∴         meals per hour = $\frac{536}{8}$

                                                    = $67$ meals per hour

$10$ chefs prepare $67$ meals per hour

then,

          meals per hour per chef  = $\frac{67}{10}$

                                                    = $6.7$ meals per hour per chef

Each chef prepare $6.7$ meals per hour

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

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