Question : Directions: Select the missing number from the given responses.
| 21 | 27 | 29 |
| ? | 96 | 142 |
| 57 | 69 | 113 |
Option 1: 46
Option 2: 69
Option 3: 29
Option 4: 78
Correct Answer: 78
Solution : Given:
| 21 | 27 | 29 |
| ? | 96 | 142 |
| 57 | 69 | 113 |
In each column, the third number is the difference between the first two numbers.
Column 2:
96 – 27 = 69
Column 3:
142 – 29 = 113
Similarly,
Column 1:
(?) – 21 = 57
⇒ (?) = 57 + 21
⇒ (?) = 78
So, 78 is the missing number. Hence, the fourth option is correct.
