Question : Directions: Find the missing number from the given responses in the following question.
Option 1: 23
Option 2: 115
Option 3: 118
Option 4: 220
Correct Answer: 115
Solution : Add the numbers of the first four rows and multiply the resultant by 5, to get the number of the fourth row.
In the first column: (1 + 2 + 4 + 3) × 5 = 10 × 5 = 50
In the second column: (3 + 4 + 5 + 2) × 5 = 14 × 5 = 70
Similarly, follow the same pattern in the third column: (7 + 4 + 9 + 3) × 5 = 23 × 5 = 115
So, 115 is the missing number in the given figure. Hence, the second option is correct.
