In the following question, a matrix of certain character is given. These characters follow a certain trend, row-wise or column-wise. Find out this trend and choose the missing character from the given alternatives.
| 3 | 5 | 8 | 7 |
| 4 | 6 | 4 | 6 |
| 5 | 2 | 2 | 4 |
| 58 | 58 | ? | 166 |
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 62
The trend runs column-wise: the number in the last row is the product of the three numbers above it, minus 2.
Column 1: \(3\times4\times5=60\), and \(60-2=58\)
Column 2: \(5\times6\times2=60\), and \(60-2=58\)
Column 4: \(7\times6\times4=168\), and \(168-2=166\)
Column 3: \(8\times4\times2=64\), and \(64-2=\) 62
