| 3) | 22 | 4) | 24 |
| 5) | None of these | ||
Answer : 22
Explanation :
Explanation :
For First Circle:
Left segment element x right segment Element - 3 = Lower number
3 x 7 - 3 = 18.
For Second Circle:
Left segment element x right segment Element - 4 = Lower number
8 x 2 - 4 = 16.
For Third Circle:
Left segment element x right segment Element - 5 = Lower number
or x = 9 x 3 -5
or x = 22.
Missing number = 22.

Answer : 12
Explanation : Logic (Row-wise):
(First Element / Second element) x 2 = Third Element.
So, (108/x) x 2 = 18
or x = 12.
Missing Number = 12.
