Multiple choice

The allocation matrix of the values - Max matrix Need Matrix A B C A B C 7 5 3 7 4 3 3 2 2 1 2 2 9 0 2 6 0 0 2 2 2 0 1 1 4 3 3 4 3 1 is

  1. A B C 0 1 0 2 0 0 3 0 2 2 1 1 2 1 2 0 0 2

  2. Allocation matrix A B C 0 1 0 2 0 0 3 0 3 2 1 1 2 1 1 0 0 2

  3. Allocation matrix A B C 0 1 0 2 0 0 3 1 2 2 1 1 2 1 1 0 0 2

  4. Allocation matrix A B C 0 1 0 2 0 0 3 0 2 2 1 1 2 1 1 0 1 2

  5. Allocation matrix A B C 0 1 0 2 0 0 3 0 2 2 1 1 2 1 1 0 0 2
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

The formula to calculate the need matrix is - Need = Max - Allocation. But we are given max and need matrices, so the formula to calculate allocation will be - Allocation = Max - Need. So, Max matrix Need Matrix A B C A B C A B C 75 3 - 7 4 3 = 0 1 0, 3 2 2 - 1 2 2 = 2 0 0, 9 0 2 - 6 0 0 = 3 0 2, 2 2 2 - 0 1 1 = 2 1 1, 4 3 3 - 4 3 1 = 0 0 2. Hence, the correct answer is - Allocation matrix A B C 0 1 0 2 0 0 3 0 2 2 1 1 2 1 1 0 0 2.
