Which number will be there in the place of question mark (?) in the following figure?
🎥 Video solution / Text Solution of this question is given below:
Look at sums along each straight line.
Vertical line: outer numbers 6 and 9, inner numbers 7 and 7.
(6 + 9) − (7 + 7) = 15 − 14 = 1
Horizontal line should follow the same pattern:
(3 + 9) − (5 + ?) = 1
12 − (5 + ?) = 1 → 5 + ? = 11 → ? = 6
