Can you solve the below algebraic mathematical equation?
(J+O+I+N+T)3 = JOINT
(1+9+6+8+3)*(1+9+6+8+3)*(1+9+6+8+3) = 19683
J = 1, O = 9, I = 6, N = 8, T = 3
How can you make the number one disappear by adding something to it?
By adding letter "G" to it. One becomes "Gone".
Is it possible to get ten whether you remove one from nine or eleven? How?
It is possible if you write numbers in their roman forms.
11 = XI
If I (1) is removed, it becomes X = 10
9 = IX
If I (1) is removed, it becomes X = 10
The following question it puts forth you:
25 - 55 + (85 + 65) = ?
Then, you are told that even though you might think its wrong, the correct answer is actually 5!
Whats your reaction to it? How can this be true?
If you read the question again, you will probably notice the slight trick used in this question.
25 - 55 + (85 + 65) = 25 - 55 + 150 = 120
Now, 120 is also equal to 5!
5! = 5 * 4 * 3 * 2 * 1 = 120
Yes, we were talking about 5! (factorial) and if you read the question, thats what is written there.
In a classic wine shop in Flobecq, Belgium, list of three most popular wines are:
- The cost of 1 French wine bottle: 500$
- The cost of 1 German wine bottle: 100$
- The cost of 20 Dutch wine bottles: 100$
Homer Simpson entered the wine shop and he needs to buy
- All three types of wine shop.
- Needs to buy Dutch wine bottles in multiple of 20.
- Need to buy 100 wine bottles
Simpson has only 10000$. How many wine bottle(s) of each type, Simpson must buy?
19(French) + 1(German) + 80(German) =>100 wines.
Cost:
19*500 + 100 + 100*4 = 10000$

Which digit occurred maximum times between the number 1 and 1000?
1
All Digits [0-9] follow the following pattern: There is one occurrence of all digits in every 10 numbers Example. Digit-9 occurred one time between 10 and 19 in 9, between 20 and 29 in 29.
However, for tens(91,92,93...99) and hundreds (900,901.... 999), the occurrence is much more. Since we have included 1000, Therefor 1 is the most occurred digit.
Note: Despite three 0s in 1000, 0 is not most occurred digit as they dont have tens and hundreds like other digits.
In a competitive exam, each correct answer could win you 10 points and each wrong answer could lose you 5 points. You sat in the exam and answered all the 20 questions, which were given in the exam.
When you checked the result, you had scored 125 marks in the test.
Can you calculate how many answers given by you were wrong ?
If all the 20 questions had been answered correctly, you would have scored a total of 200 marks. Since you scored 125 marks, you have lost 75 marks.
Now, what you have to do is subtract 15 marks from 200 for every wrong answer. This is because you have to deduct 10 marks for not scoring in that question and 5 marks for answering it wrong.
15 * 5 = 75
Therefore, you answered 5 questions wrong.
