Question Detail:

If someone travels for business purpose which is more than 48 miles away, will they do qasr for any namaaz which come in between? 

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
When you intend to travel for 48 miles or more, then the moment you left the boundaries of your city you will read two raka’āt instead of four raka’āt of Salāh in Ðuhur, Ἀṣar and Ἰshā until you re-enter the boundaries of your city. As such, you will do qasar for any Namāz that comes in between.[i]
And Allah Ta’āla Knows Best
