Answer: Third option is correct.
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://img.qammunity.org/2021/formulas/mathematics/high-school/qcwbfqq4hfputnuw8jpzjjc46cp0dnff46.png)
New receipts = 21, 145 and 11
So, Number of watches on hand becomes :
![190+(21+145+11)\\\\=367](https://img.qammunity.org/2021/formulas/mathematics/high-school/uuva5ujwb9kn0at15695h7isyp3hjwlz1y.png)
Hence, Third option is correct.
