Did you get it right?
This number-grid puzzle gives two numbers on the left and one result on the right. The challenge is to find the same rule for the missing result.

The Answer
The correct answer is: 35.
Here is why
- Use this rule for each row: first number times second number, then add the first number.
- 3×8 + 3 = 27.
- 5×6 + 5 = 35.
- 7×4 + 7 = 35.
Why people miss it
Many people multiply the two numbers but forget the extra first number at the end.
