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 :
![1000-(168+231+411)\\\\=1000-810\\\\=190](https://tex.z-dn.net/?f=1000-%28168%2B231%2B411%29%5C%5C%5C%5C%3D1000-810%5C%5C%5C%5C%3D190)
New receipts = 21, 145 and 11
So, Number of watches on hand becomes :
![190+(21+145+11)\\\\=367](https://tex.z-dn.net/?f=190%2B%2821%2B145%2B11%29%5C%5C%5C%5C%3D367)
Hence, Third option is correct.
