Question : Directions: In the following question, select the missing number from the given responses.
Option 1: 121
Option 2: 82
Option 3: 131
Option 4: 74
Correct Answer: 131
Solution : Here, the product of numbers on opposite sides and the sum of their resultants gives the middle number.
Like, (4 × 6) + (6 × 7) = 24 + 42 = 66
And, (8 × 9) + (14 × 5) = 72 + 70 = 142
Similarly, (6 × 9) + (11 × 7) = 54 + 77 = 131
So, the missing number is 131. Hence, the third option is correct.
