If four people can make 24 chairs in 2 hours how many chairs can 5 people make in three hours?

4 people can make 24 chairs in 2 hours

So 1 person can make 6 chairs in 2 hours.

So 5 people can make 30 chairs in 2 hours

So 5 people can make 90 chairs in 6 hours.

So 5 people can make 45 chairs in 3 hours. 



---------------------------

Or you can use the "workers-times-jobs" formula:

 = 

where

W1 = number of workers in the first situation = 4
W2 = number of workers in the second situation = 5
T1 = number of time units in the first situation = 2
T2 = number of time units in the second situation = 3
J1 = number of jobs done in the first situation = 24
J2 = number of jobs done in the second situation = ?

 = 

Substituting:

 = 

 = 

 = 

J2 = 45
