OD,Explanation / Answer
Information given:
Machine hours in Cutting department = 1590
Machine hours in Assembly department = 3030
Machine hours in Finishing department = 2480
For manufacturing,
A chair requires: 0.2 hours of Cutting, 0.8 hours of Assembly, and 0.5 hours of Finishing.
A cabinet requires: 0.5 hour of Cutting, 0.1 hour of Assembly, and 0.2 hours of Finishing.
A buffet requires: 0.3 hours of Cutting, 0.9 hours of Assembly, and 0.8 hours of Finishing.
Now, let's say 'x' chairs, 'y' cabinets, and 'z' buffets are to be made in order to use all the production capacity available.
Therefore, for 'x'chairs, 'y' cabinets, and 'z' buffets need 1590 hours from Cutting department, 3030 hours from Assembly department, 2480 hours from Finishing department.
That leads us to the following linear equations:
0.2x+0.5y+0.3z=1590
0.8x+0.1y+0.9z=3030
0.5x+0.2y+0.8z=2480
The answer which is option B.
Finally, we remained with 3 equations and 3 unknowns which are easily solvable.
By solving above three linear equations we get :
the number of chairs(x)=1800
the number of cabinets(y)=1500
the number of buffets(z)=1600.
