Consider the following Saaty's pairwise comparison matrix for the assessment of the importance of criteria A$,$ B$,$ C and D$.$

Fill in the missing values so that the resulting matrix is reciprocal, calculate the normalized weights of criteria A$,$ B$,$ C$,$ and D that correspond well with the preference information contained in the matrix. Suggest the ordering of the criteria from the most important to the least important one. Decide, whether the matrix is completely consistent or not, justify your answer and explain what it implies for the calculated weights.
