[Show Answer]


Trash in cotton fed to beater=4%


Waste contains=60% trash

Cleaning efficiency of beater=?


Trash extracted by beater=60% x 2/100

Trash extracted by beater=1.2%

Cleaning efficiency%=(Fed trash%-Extracted trash%) x 100/Fed trash

Cleaning efficiency%=(4-1.2) x 100/4

Cleaning efficiency%=70%
