Well, well. That wasn’t too hard, was it? Curious how you fared? Read below for the answers.


Note that 1 person in the Gryffindor team and 2 people in the Slytherin team did not answer, hence the Gryffindor team got the average of their team added to their score once and the Slytherin team got the average of their team added to their score twice.


Mathematical Quirk Questions

1) If you multiply 9 with 75 you get 675. How do you get 9 again without using a divide or multiply?

2) If you multiply 9 with 275 you get 2475. How do you get 9 again without using a divide or multiply?

3) Take 9485 and arrange it in ascending and descending order. Then subtract the smaller number from the larger number. Keep repeating this step until you get to Kaprekar’s Constant. How many steps did it take and what is Kaprekar’s Constant?

4) Take 3745 and arrange it in ascending and descending order. Then subtract the smaller number from the larger number. Keep repeating this step until you get to Kaprekar’s Constant. How many steps did it take and what is Kaprekar’s Constant?

5) If you have the numbers 111 and 222, how do you get to 37 from them and what is the common link between those 2 solutions?

6) If you have the numbers 444 and 555, how do you get to 37 from them and what is the common link between those 2 solutions?

7) Take any 3-digit number and write it twice to make it into a 6-digit number (such as 456 becomes 456,456). What 3 digits will any such number be exactly divisible by each time without any remainder?

8) Take any 3-digit number and write it twice to make it into a 6-digit number (such as 677 becomes 677,677). What 3 digits will any such number be exactly divisible by each time without any remainder?

9) What is the only number whose letters appear in alphabetical order once it is written out (like two, three, etc.)?

10) What is the only number whose letters appear in reverse alphabetical order once it is written out (like two, three, etc.)?

11) What is a letter you wouldn’t use until you reached “one thousand” if you were spelling each number out?

12) What is a letter you wouldn’t use until you reached “billion” if you were spelling each number out?

13) What is the only number that cannot be represented using Roman numerals unless you include an operation in it?

14) What is the name “Google” a misspelling of and what does that original word represent?

15) What is an easy way to find out how long it would take to double your money with compound interest?

16) On a standard six-sided die, what do opposite sides always add up?

Mathematical Quirk Answers

1) Add the digits 6 + 7 + 5 to get 18 and then add those digits to get 9. This is known as the power of 9 where any time you multiply a number by 9 and keep adding the digits, you get 9 again at some point.

2) Add the digits 2 + 4 + 7 + 5 to get 18 and then add those digits to get 9. This is known as the power of 9 where any time you multiply a number by 9 and keep adding the digits, you get 9 again at some point.

3) Kaprekar’s Constant is 6174 which is a number you will reach in 7 steps or less each time when you take any 4-digit number with at least 2 different digits and repeat the process of ascending and descending order. For 9485, the number 6174 is reached in 5 steps.

4) Kaprekar’s Constant is 6174 which is a number you will reach in 7 steps or less each time when you take any 4-digit number with at least 2 different digits and repeat the process of ascending and descending order. For 3745, the number 6174 is reached in 7 steps.

5) If you divide 111 by the sum of its digits and 222 by the sum of its digits you get to 37. This works for any three-digit number where all 3 digits are the same.

6) If you divide 444 by the sum of its digits and 555 by the sum of its digits you get to 37. This works for any three-digit number where all 3 digits are the same.

7) Any 3-digit number written twice to make a 6-digit number will always be exactly divisible by 7, 11, and 13 without any remainder.

8) Any 3-digit number written twice to make a 6-digit number will always be exactly divisible by 7, 11, and 13 without any remainder.

9) Forty

10) One

11) The letter “A”

12) The letter “B”

13) Zero

14) It’s a misspelling of “googol” which is the number 1 followed by 100 zeroes

15) Divide 72 by the interest rate, so 6% would be 72 / 6 = 12 years

16) The number 7 (1 + 6, 2 + 5, 3 + 4)

Math Riddle Questions

1) In this family, a girl has as many as brothers as she has sisters, but a boy has only half as many brothers as he has sisters. How many brothers and sisters are there in the family?

2) Which is heavier: 100 kgs of lead or 100 kgs of feathers?

Welcome students. I bring to you a very simple class. My name is Professor Burbage.

You’ve all been amongst Muggles for a while now and still live amongst them. However, there are some wizards who haven’t been amongst Muggles for years now. One such person is with us today. Please welcome Arthur Weasley.

Arthur has a very simple question for all of you. What is the purpose of a slinky?

You will submit a maximum 500-word response to this very simple question as a House. This means I want only 4 responses – one from each House. Only the Head Girl needs to PM me or, if they are busy, any 1 member from each House.

I will grade each response out of 3000 points – 1000 points for creativity, 1000 points for originality, and 1000 points for how well you answer the question without sounding condescending or rude. If you use AI for this round, it will lead to an automatic 0 overall for this round. There will a second grader who will also grade this round out of 3000 points similar to above, but if I mark it 0 for AI then that person won't be grading.

Note that this time around the score will be added to only the House score!

The deadline for this submission is May 8 11:59 PM IST.
