Answer 1

Solution.

For unit 1 of round top computer desk = 4 units of B + 2 units of C + 8 units of D + 7 units of E + 3 units of F required as per the diagram given.

Computer desk already available on hand.1

So only 9 units of computer desk is required.

So for 9 units of round up of computer desk = 9 * ( 4 units of B + 2 units of C + 8 units of D + 7 units of E + 3 units of F ) required.

So for 9 units of round up of computer desk = 36 units of B + 18 units of C + 72 units of D + 63 units of E + 27 units of F required /

But below is the availability

B = 8 units

C = 6 units

D = 100 units

E = 48 units

F = 20 units.

Following is the requirement of B.

B = 4*9= 36

On hand inventory = 8

Balance requirement of B = 36 - 8 = 28 units

Following is the requirement of C

C = 2*9 = 18

On hand inventory = 6

Balance requirement of C= 18-6 = 12 units

Balance requirement of D = 0 as D requirement is only 72 units and stock on hand is 100.

Balance requirement of E = 63 - 48 = 15 units

Balance requirement of F = 27 - 20 = 7 units.

The above balance requirement of all the parts need to procured to satisfy a new order of 10 round top computer desks.
