Answer: 30 days
Explanation: Cash cycle refers to the amount of time it takes for a business from paying cash to its suppliers for raw materials and receiving cash from its customers fro the sales made.
Hence from the above we can say that :-
decrease in inventory will decrease the cycle.
Decrease in receivables will decrease the cycle.
decrease in payables will increase the cycle.
Thus,
cash cycle = 31 days - 2 days + 4 days - 3 days
= 30 days
