Math Brain Teasers with answers
The Missing Number Riddle
What is the missing number in the following sequence? 8, 6, 14, 12, 22, 20, 28, ?
Click to Find Answer
Solution: The sequence follows a pattern of adding 2 and then 8. Therefore, the next number in the sequence would be 36.
The Four-Digit Number Riddle.
What is the four-digit number in which the first digit is one-fourth of the second, the third digit is the sum of the first two, and the last digit is three times the second?
Click to Find Answer
Solution: Let's call the number ABCD, where A is the first digit, B is the second digit, C is the third digit, and D is the fourth digit. From the given information, we can create the following equations:
A = B/4
C = A + B
D = 3B
Substituting the first equation into the second equation, we get:
C = B/4 + B = 5B/4
Substituting the third equation into the fourth equation, we get:
D = 3B
Combining the second and third equations, we get:
C = A + B = B/4 + B = 5B/4
Substituting the third equation into the second equation, we get:
5B/4 = 3B
Solving for B, we get:
B = 8
Substituting B = 8 into the first equation, we get:
A = B/4 = 2
Substituting A and B into the third equation, we get:
C = A + B = 2 + 8 = 10
Substituting B into the fourth equation, we get:
D = 3B = 3(8) = 24
Therefore, the four-digit number is 2810.
The Ages Riddle
A father is four times as old as his son. In 20 years, the father will be twice as old as his son. How old are they now?
Click to Find Answer
Solution: Let's call the son's current age S and the father's current age F. From the given information, we can create the following equations:
F = 4S F + 20 = 2(S + 20)
Substituting the first equation into the second equation, we get:
4S + 20 = 2S + 40
Solving for S, we get:
S = 10
Substituting S = 10 into the first equation, we get:
F = 4(10) = 40
Therefore, the son is 10 years old and the father is 40 years old.
The Two-Children Riddle
A man has two children. One is a boy. What is the probability that the other child is also a boy?
Click to Find Answer
Solution: There are four possible combinations of genders for two children: BB, BG, GB, and GG,where B represents a boy and G represents a girl.
The information given in the riddle tells us that one of the children is a boy. This eliminates the possibility of the GG combination, leaving us with three possible combinations: BB, BG, and GB. Therefore, the probability that the other child is also a boy is 1/3.
