Reels produced per day = 800
Production cut = 1/5
Let, the daily production be 1.
therefore,
New per day production = 1-
New per day production = 4/5
Therefore,
4/5 of 800 = New no. of reels produced per day
= New no. of reels
640 = New no. of reels
New. no of reels produced per day = 640
Reels produced in 30 days = 640*30 = 19200
