Math Riddles: Missing Number Math Puzzles
Logic Puzzle #1
Logic Puzzle #2
Logic Puzzle #3

Logic Puzzle #4

Solution
Logic Puzzle #1
Answer: 73
Explanation
We will first solve the Shape 1 and Shape 2 to understand the logic.
(9 x 3) + (4 + 5) + (2 x 7) = 61 Shape 2 => (6 x 6) + (3 x 8) + (7 + 4) = 88 Similarly, we shall apply the same logic to solve the Shape 3. Shape 3 => (5 x 3) + (6 x 7) + (8 x 2) = 73 Logic Puzzle #2 Answer: 16 Explanation We will start by solving Circle 1 and Circle 2 to figure out the logic. Circle 1 => 9 x 8 / 2 = 36 Circle 2 => 6 x 7 / 2 = 21 Similarly, we shall apply the same logic to find out the missing number in the place of the question mark. Circle 3 => 4 x 8 / 2 = 16 Tell us in comments: Did you solve these math puzzles in 20 seconds each? Check out more math puzzles!" width="164" height="142">
