For the purpose of proving, I factored in just one variable that is 'CREDIT'
For example,
Credit = 60 days
No of days to sell 10 quantities = 20 days implies a single qty takes 2 days to sell
Maximum Possible Cycles = Purchase - Hold - Sell - Purchase again = 60/20 = 3 cycles
Carefully look at the following information in the picture
Pure Product - Single bill comes with 20 qty
Hybrid - Single bill comes with 13 qty and cash in hand
Less Quantities = Less Inventory Cost = More Cycles = More Profit
At the end of the 60th day,
Pure Product Offer - 2 Bills with 10 quantities in hand + 1.5 cycles
Hybrid - 3 bills with 9 quantities in hand + 2.3 cycles
Profit of Hybrid > Profit Pure Product Offer
This can further be proven by factoring in inventory cost, labour cost, Tax saving etc
