Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
Total watches in an inventory = 1000
Number of shipments sent out = 168, 231, 411
So, Remaining inventory of watches would be :
[tex]1000-(168+231+411)\\\\=1000-810\\\\=190[/tex]
New receipts = 21, 145 and 11
So, Number of watches on hand becomes :
[tex]190+(21+145+11)\\\\=367[/tex]
Hence, Third option is correct.
