1. Upper middle
2. Upper left
3. From any arbitrary cell in first row
4. Upper right

Correct answer: Upper left

Q2. Which method is expected to give a better initial solution among NWC, LCM, and VAM?

1. All methods provide similar initial solutions
2. NWC
3. LCM
4. VAM

Correct answer: VAM

Q3. The Transportation and Transshipment Models are types of ---------------- models.

1. Variation
2. Inventory
3. Allocation
4. Network

Correct answer: Network

Q4. What is the significance of selecting the row or column with the largest penalty in VAM?

1. It denotes the final allocation step
2. It prioritizes the allocation to minimize penalties
3. It indicates the highest transportation cost
4. It represents the maximum supply or demand

Correct answer: It prioritizes the allocation to minimize penalties

Q5. A balanced transportation model with ‘5’number of sources and ‘7’ destinations has -------- number of constraint equations.

1. 12
2. 10
3. 2
4. 35

Correct answer: 12

Q6. How is the least cost method (LCM) different from the Northwest Corner rule (NWC)?

Correct answer: Dual

Q10. For North West Corner method, in the first row and first column, each source and sink contain ‘5’ units ; then after allocating the appropriate amount ‘x11’ in the cell (1,1), we will move towards which of the following cell?

1. Towards (2,1) if 2nd row contains more occupied cells than 1st row
2. Neither towards (1,2) nor (2,1) but move diagonally towards (2,2)
3. Towards (1,2) if 1st row contains more occupied cells than 2nd row
4. Arbitrarily either towards (1,2) or (2,1)

Correct answer: Neither towards (1,2) nor (2,1) but move diagonally towards (2,2)
