About This Quiz

Puzzles and brain teasers that require logical skills involve critical thinking, pattern recognition and deduction skills. If you believe you're a logical person by nature, then this difficult logic quiz is for you!

This quiz is full of riddles, "What Am I" questions, numerical and alphabetical patterns, brain teasers and more! So to help you prepare for this quiz, we're giving you a couple of warm-ups to practice with.

Let's start with a numerical pattern. Can you recognize the pattern in this sequence: 1, 3, 5, 7, 9? The pattern is that each number is increased by 2. (1 +2 is 3, 3+ 2 is 5 and so forth). Some questions will also make you think about what letter or word comes next in the pattern!

Other questions will also involve a little bit of math and numerical conversions. For example, do you know what 5% of 50 is? Well, if you can deduce that 10% of 50 is 5, then 5% of that should be 2.5!

If you think you're ready to score a 100% on our most difficult logic quiz to date, it's time to show us what you're made of by using all the brain power you've got!

If a $20 shirt is 15% off, what is the final price of the shirt?

The answer is $17. 15% of 20 is 3, so 20-3 is 17.

3 of 35
If X=24 and P =16, what is X-P-A?
7
6
9

7 is the correct answer. The letters correspond to its numerical place in the alphabet. X is the 24th letter in the alphabet and P is the 16th letter in the alphabet. Going by this, A is the first letter in the alphabet. So, the problem really becomes 24-16-1=7.

4 of 35
What is the next number in the pattern: 16, 25, 36, 49, _____.

64 is the correct answer. The numbers in the answer represent a list of perfect squares, so the next perfect square would be 64 (8 times 8 is 64).

5 of 35
What is the next letter in this pattern: B, E, H, K, _____.
P
O
M
N

N is the correct letter. Each letter corresponds to a number in the alphabet, and each number is added by 3. So, B is 2 and 2 + 3 is 5, which is E in the alphabet. This pattern repeats itself until you get to K, which is the 11th letter in the alphabet. 11 + 3 is 14, which is N in the alphabet (the right answer).

6 of 35
What do these things have in common: Apples, Elephants, Oranges, Irises and Utah?

If 1 yard equals 3 feet, and I need 10 yards of wood to build a house, how many feet would that be?

The answer is 30. If 1 yard = 3 feet, than 10 yards = 30 feet (you just multiply 10 by 3).

8 of 35
I am followed by 25 others and represent the number 1. What am I?

The answer is "A." A is the first letter in the alphabet and is followed by 25 other letters.

9 of 35
If x = 1 and y = 2, what is 2xy?
5
3
2
4

The answer is 4. 2xy is another way of saying 2 times x times y. If x is 1 and y is 2, that means 2 times 1 times 2 is 4.

10 of 35
If A is blue and B is yellow, then what is A + B?

4
8
9
