Option 1: 10
Option 2: 18
Option 3: 11
Option 4: 12
Correct Answer: 12
Solution :
Given:
9 @ 8 @ 7 = 24, 4 @ 7 @ 3 = 14
Here, replace @ with +;
Like, 9 @ 8 @ 7 = 24→9 + 8 + 7 = 24,
And, 4 @ 7 @ 3 = 14→4 + 7 + 3 = 14
Similarly, follow the same pattern for 2 @ 1 @ 9 =?→2 + 1 + 9 = 12
So, the missing term is 12. Hence, the fourth option is correct.
