And 3… 2… 1! Time is up!
Did you crack it? If “Yes”, then you have a better logical thinking. If not, it's okay, it's supposed to challenge you.
Here is the solution for this puzzle.
Find the Value: Solution
The key is to notice that the answer is made up of three separate calculations using the two numbers (let's call them A and B):
-
First part = A × B
-
Second part = A + B
-
Third part = A - B
Let's verify with the given equations:
-
8 × 2 = 16, 8 + 2 = 10, 8 − 2 = 6, gives 16106
-
5 × 4 = 20, 5 + 4 = 9, 5 − 4 = 1, gives 2091
-
9 × 6 = 54, 9 + 6 = 15, 9 − 6 = 3, gives 54153
-
7 × 5 = 35, 7 + 5 = 12, 7 − 5 = 2, gives 35122
The pattern is: A×B, A+B, A−B which are all combined into one number.
Now for 20 + 3:
-
20 × 3 = 60
-
20 + 3 = 23
-
20 − 3 = 17
Answer: 602317
