(N4, N7, N5, N8) will be in middle or the lowest shelf.

Note that any reference book of one subject can be absent from only one shelf.

N2 and Biology reference book are not on one shelf

Similarly N6 and N8 are on middle and the lowest shelves respectively.

N5 and History reference book are not on one shelf and N5 is in middle or the lowest shelf One of these shelves will also not have History reference book and that shelf will only have two reference book.

we can have two different arrangements:

The XYZ manufacturing company produces a product which has 6 month demand cycle as given below:

Month	Demand in Units	Working days/month
January	600	22
February	1000	19
March	800	21
April	200	21
May	400	22
June	600	2

Company's policy is to retain safety stock of 20% of monthly demand and each month's safety stock becomes the opening stock for the next month, and opening stock for January is 100 units. Each unit requires 10 labour-hours and company works 8 hour/day.

If there are currently 20 workers employed, and how many worker are needed to be laid off in January to accommodate demand?
