Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
| 12 | 4 | 11 | 33 |
| 13 | 2 | 6 | 39 |
| 14 | 7 | 5 | 10 |
| 18 | ? | 2 | 9 |
Option 1: 3
Option 2: 5
Option 3: 8
Option 4: 4
Correct Answer: 4
Solution : Multiply the first and third columns and divide the resultant by the second column, to get the fourth column –
In the first row: (12 × 11) ÷ 4 = 132 ÷ 4 = 33
In the second row: (13 × 6) ÷ 2 = 78 ÷ 4 = 39
In the third row: (14 × 5) ÷ 7 = 70 ÷ 7 = 70
Similarly, follow the same pattern in the fourth row: (18 × 2) ÷ ? = 9 ⇒ ? = 36 ÷ 9 = 4
So, from the above, 4 is the required number of the given figure. Hence, the fourth option is correct.
