| 1 | 4 |
| 10 | 7 |
| 5 | 8 |
| 14 | 11 |
| 6 | 9 |
| ? | 12 |
Option 1: 13
Option 2: 14
Option 3: 15
Option 4: 16
Correct Answer: 15
Solution : In each figure, starting from the top left corner add 3 in each number in a clockwise direction, to get the required missing number.
In figure one: 1 + 3 = 4; 4 + 3 = 7; 7 + 3 = 10
In figure two: 5 + 3 = 8; 8 + 3 = 11; 11 + 3 = 14
Similarly, follow the same pattern in figure three: 6 + 3 = 9; 9 + 3 = 12; 12 + 3 = 15
So, the missing number is 15. Hence, the third option is correct.
