Explanation:

- Total Sales Ratio: The companies A, B, and C have a total sales ratio of 7 : 9 : 6.

- Company C: Sold 192 digital watches. Analog watches account for 60% of total sales at Company C. Therefore, digital watches make up 40%, implying Company C's total sales are $\frac{192}{0.4}=480$.

- Analog sales by Company C: 60% of 480, which equals 288 watches.

- Company B: The number of analog watches sold equals the sum of analog and digital watch sales of Company C, which is 480.

- Company A: Sells watches in a 5:3 ratio of digital to analog watches. Therefore total sales of A are $7x=840$.

- Analog sales by Company A: $\frac{3}{8}\times 840=315$.

Calculating total analog sales:

- Company A: 315

- Company B: 480

- Company C: 288

- Total across all companies: $315+480+288=1083$
