Select the missing number from the given options:
| 18 | 28 | 50 |
| 17 | 13 | 11 |
| 26 | 27 | ? |
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 36.
In every column: Number in 1st row = 2 × (Number in 3rd row – Number in 2nd row)
1st column: (26 – 17) = 9, 9 × 2 = 18
2nd column: (27 – 13) = 14, 14 × 2 = 28
Similarly, 3rd column:
50 ÷ 2 = 25
25 = x – 11
x = 25 + 11 = 36
