A matrix contains four rows (I, II, III, and IV) from top to bottom and four columns (I, II, III, and IV) from left to right. A word is formed when we go left to right in a row and top to bottom in a column. Conditions: 1. No letters are repeated more than twice. 2. If a column/row has one letter, the entire column/row should not have that letter. 3. Alphabets are coded as A1, B2, C3, D4, E5, F1, G2, H3, ... , Z1. 4. Place values of column and row are added to get the cell value of a particular row or column. 5. A meaningful letter has to be formed in each column. Column I: positions I, II, and IV contain V, A, and T respectively. Column II: positions III and IV contain H and O respectively. Column III: position II contains R. Column IV: positions I, III, and IV contain N, T, and S respectively. What is the difference between the value of column I and row II?
- Eight
- Two
- Six
- Zero
Correct answer: Zero
Solution
Using the code A1, B2, C3, ... the letters in column I and row II lead to the same total value after adding their place values. Since both totals are equal, their difference is zero. The question is a matrix-based coding arrangement problem.
