Alright, lets get started.
If Matthew wants to complete packages at an average rate of at least 39 packages per hour.
And they worked 4 hrs only due to picnic, yesterday, it means they have to make
packages.
But they made only 112 packages means they are short of
packages.
Suppose they are working today t hrs, and his department will complete 43 packages per hour today.
It means they are going to make 43 t packages today.
This 43 t packages includes those 44 too , which they are short of yesterday due to picnic.
So, average will be
(39 average given in question)
Cross multiplying
![39 t = 43 t - 44](https://tex.z-dn.net/?f=%2039%20t%20%3D%2043%20t%20-%2044%20)
Adding 44 in both sides
![39 t + 44 = 43 t - 44 + 44](https://tex.z-dn.net/?f=%2039%20t%20%2B%2044%20%3D%2043%20t%20-%2044%20%2B%2044%20)
![43 t = 39 t + 44](https://tex.z-dn.net/?f=%2043%20t%20%3D%2039%20t%20%2B%2044%20)
Subtracting 39 t in both sides
![43 t - 39 t = 39 t + 44 - 39 t](https://tex.z-dn.net/?f=%2043%20t%20-%2039%20t%20%3D%2039%20t%20%2B%2044%20-%2039%20t%20)
![4t = 44](https://tex.z-dn.net/?f=%204t%20%3D%2044%20)
Dividing 4 in both sides
t = 11 hrs
Hence they have to woth 11 hrs today : Answer
Hope it will help :)
