# Find the Missing Number from Table Given Below

11 | 10 | 9 |

7 | 15 | 8 |

12 | 5 | ? |

- 9
- 10
- 13
- 17

**Answer: 13**

Explanation: The addition of all three numbers in a column of this table is equals to 30.

like: 11 + 7 + 12 = 30

10 + 15 + 5 = 30

That’s why, 9 + 8 + ? = 30

After solving this: 30 – (9 + 8) = 30 – 17 = 13

So 13 should be the right answer.
