## Solution

### Logic Puzzle #1

Explanation

We will first solve Shape 1 and Shape 2 to understand the logic.

Shape 1

=> (12 + 4) x (8 – 5)

=> 16 x 3

=> 48

Shape 2

=> (15 + 4) x (11 - 5)

=> 19 x 6

=> 114

Similarly, we shall apply the same logic to solve Shape 3.

Shape 3

=> (18 + 3) x (18 - 12)

=> 21 x 6

=> 126

Hence, the missing number in Shape 3 is 126.

### Logic Puzzle #2

Explanation

We will start by solving Circle 1 and Circle 2 to figure out the logic.

Circle 1

=> (7 x 8) – (7 + 8) = 41

Circle 2

Moving on, we solve this circle with the same logic.

=> (5 x 9) – (5 + 9) = 31

Similarly, we shall apply the same logic to find out the missing number in the place of the question mark.

Circle 3

=> (11 x 7) – (11 + 7)

=> 59
