In the following question, which character when placed at the sign of (?) shall complete the matrix?
| 4C | 2B | 3A |
| 28A | 10C | ? |
| 7C | 5A | 15B |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 45B
The numbers and the letters follow two separate rules:
Numbers, column by column: the middle number is the product of the top and bottom numbers.
Column 1: \(4\times7=28\)
Column 2: \(2\times5=10\)
Column 3: \(3\times15=45\)
Letters, row by row: each row uses A, B and C once. Row 1 has C, B, A and row 3 has C, A, B; row 2 has A and C, so the missing letter is B.
