Mathematical Number Puzzle: Can you replace the question mark?
Here is a mathematical number puzzle that will twist your mind. In this logical reasoning puzzle, some numbers in a shape are given, which are correct logically. Can you find the logic behind these problems and then replace the question mark?
Mathematical Number Puzzle: Can you replace the question mark?
Problem 1 (Left):
Top-left = 3
Top-right = 10
Bottom-left = 4
Bottom-right = 15
Center = 77
⇒ Logic: (top right – top left ) x ( bottom right – bottom left )
⇒ (10 – 3 ) x (15 – 4)
⇒ 7 x 11
⇒ 77
Apply the Rule to Problem 2 (Right):
Top-left = 10
Top-right = 20
Bottom-left = 16
Bottom-right = 30
Center =?
⇒ Logic: (top right – top left) x (bottom right – bottom left)
