Answer:
 8.78
Step-by-step explanation:
The computation of the cash cycle is given below;
We know that
Cash cycle = Inventory conversion period + Receivables conversion period - Payables conversion period. 
 Here
1. Inventory conversion period = Avg. Inventory ÷ (COGS ÷365) 
= (11,000) ÷ (395000 ÷ 365) 
= 10.16 
 2. Receivables conversion period = Avg. Accounts Receivable ÷ (Credit Sales × 365) 
= (27000/520000) × 365 
 = 18.95 
 3. Payables conversion period = Avg. Accounts Payable ÷ (Purchases × 365) 
 = (22000 ÷ 395000) × 365 
= 20.33
Now the cash cycle is 
= 10.16 + 18.95 - 20.33
= 8.78
