Correct Answer: 13
Solution : Given:
| 8 | 9 | 9 |
| 6 | 7 | 8 |
| 9 | 11 | ? |
| 39 | 52 | 59 |
The pattern can be observed running vertically down in the columns.
Column 1:
(8 × 6) – 9 = 48 – 9 = 39
Column 2:
(9 × 7) – 11 = 63 – 11 = 52
Column 3:
(9 × 8) – (?) = 59
⇒ 72 – (?) = 59
⇒ (?) = 72 – 59
⇒ (?) = 13
So, 13 is the missing term. Hence, the fourth option is correct.
