Answer 1

no they dont need to make more pens...and 120 extra pens are lying in factory..

144 pens in one carton so
144*395=56880
so accordingly 57000-56880 pens lying in factory

Answer 2

No of ball pens = 57000
No of ball pens in a carton = 144
No of carton to be filled =395
No of ball pens filled in 395 carton= 395×144=56880
No of ball pens left= 57000-56880=120
