Question

Solve the mathematical puzzle.

Determine the digits of F from these clues.

The digits of F are all the same.
The sum of all the digits of F is 12.
The answer when any two of the digits are multiplied together is also 9.

F is a four-digit number.

Answer 1

3,3,3,3

Step-by-step explanation for checking my work:

f are all the same T/F T

the sum of all the digits are 12 T/F T

when any two are multiplied together it is 9 T/F T

all are true so the answer is correct

Answer 2

F = x
F = x + x + x + x = 12
4x = 12
x = 3

any two digits are multiplied is 9,
3 × 3 = 9

Therefore,the digits of F are 3,3,3,3
