  2. Your Mobile

  3. Your Study books

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Your name belongs to you, but other people use it more frequently than you do because they say it when calling or addressing you. You rarely say your own name, while others use it constantly to refer to you. This is a classic riddle that plays on the difference between ownership and usage frequency.

Multiple choice general knowledge math & puzzles

Bob and John form a team together. Bob is as old as John will be when Bob is twice as old as John was when Bob was half as old as the sum of their current ages. John is as old as Bob was when John was half as old as he will become over ten years. How old are Bob and John?

  1. John is 35 years old and Bob 45.

  2. John is 30 years old and Bob 40.

  3. John is 40 years old and Bob 50.

  4. John is 30 years old and Bob 20.

B Correct answer
Explanation

Let Bob's age = B and John's age = J. Solving the complex system of equations yields B = 40 and J = 30. The second statement gives us the key equation: J = (B/2) + 10, which with B = 40 gives J = 30. This pair satisfies the conditions of both statements. Option A (35, 45) and Option C (40, 50) don't satisfy the second condition, while Option D has ages in the wrong order.

What has three feet, but no toes?

  1. A Traingle

  2. A Yardstick

  3. A three wheeler

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A yardstick has three feet (3 linear feet = 1 yard), but no toes. This is a classic riddle that plays on the dual meaning of 'feet' - as a unit of measurement versus body parts. A triangle has sides, not feet, and a three-wheeler has wheels, not feet.

Multiple choice general knowledge math & puzzles

Haretown and Tortoiseville are 30 miles apart. A hare travels at 7 miles per hour from Haretown to Tortoiseville, while a tortoise travels at 3 miles per hour from Tortoiseville to Haretown. If both set out at the same time, how many miles will the hare have to travel before meeting the tortoise en route?

  1. 22

  2. 21

  3. 20

  4. 19
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The hare and tortoise travel toward each other, so their combined speed is 7 + 3 = 10 mph. To cover 30 miles, they need 30/10 = 3 hours. In 3 hours, the hare travels 7 × 3 = 21 miles before meeting the tortoise. Option A (22 miles) and Option C (20 miles) are incorrect calculations, while Option D doesn't match the mathematical result.

Multiple choice general knowledge math & puzzles

Glenn and Jason each have a collection of tennis balls. Glenn said that if Jason would give him 2 of his balls they would have an equal number; but, if Glenn would give Jason 2 of his balls, Jason would have 2 times as many balls as Glenn. How many balls does Jason have?

  1. 17

  2. 15

  3. 14

  4. 16
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Let G = Glenn's balls, J = Jason's balls. From the first statement: G + 2 = J - 2, so J = G + 4. From the second: J + 2 = 2(G - 2). Substituting J: G + 4 + 2 = 2G - 4, which gives G = 10 and J = 14. Option A (17), B (15), and D (16) don't satisfy both conditions simultaneously.

Multiple choice general knowledge math & puzzles

How many times can you subtract the number 5 from 25?

  1. 0

  2. 1

  3. 2

  4. 5
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

You can only subtract 5 from 25 once, because after that you're subtracting from 20, not from 25. This is a classic trick question - it asks how many times you can subtract 5 'from 25' specifically, not how many times you can subtract 5 repeatedly. Option D (5) assumes repeated subtraction from changing numbers, while Option A (0) and C (2) are simply incorrect.

Multiple choice general knowledge math & puzzles

Man Wrinkle spent one-fourth of his life as a boy, one-eighth as a youth, and one-half as an active man. If Man Wrinkle spent 12 years as an old man, then how many years did he spend as an active man?

  1. 48

  2. 47

  3. 49

  4. 50
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Let total life = L. The fractions for boy + youth + active man = 1/4 + 1/8 + 1/2 = 7/8. So old age (12 years) = L - 7L/8 = L/8. This means L = 96 years total. Active man years = L/2 = 96/2 = 48 years. Options B (47), C (49), and D (50) are incorrect and don't result from the fraction calculation.

Multiple choice general knowledge math & puzzles

A man had 12 sheep. All but 9 died. How many sheep did he have left?

  1. 6

  2. 3

  3. 9

  4. 12
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The phrase 'all but 9 died' means that 9 sheep survived and the rest died. Since he started with 12 sheep and 'all except 9' died, he has 9 sheep left. This is a trick question - people often mistakenly subtract 9 from 12 (getting 3) or misread 'all but' as 'all'. Option A (6) and B (3) are common errors, while D (12) ignores that some sheep died.

Multiple choice general knowledge math & puzzles

It was Helen's first day at school. The teacher suggested that it would be a good idea for each child to meet every other child in the class. The teacher said, "When you meet, please shake hands and introduce yourself by name." If there were 13 children in the class, how many total handshakes were there?

  1. 77

  2. 76

  3. 78

  4. 79
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

With 13 children, each child shakes hands with 12 others. This gives 13 × 12 = 156 handshake instances, but each handshake involves 2 people, so we've counted each handshake twice. The actual number is 156/2 = 78 handshakes. Using the formula n(n-1)/2 for n people: 13 × 12/2 = 78. Options A (77) and B (76) are incorrect, while D (79) doesn't result from the correct formula.
