Decimals Math Riddle Solution
Hopefully, you had fun solving this decimals riddle and got the answer on time. Now it’s time to check if you came up with the correct solution.
From reading the clues we infer that the number has two digits on the whole number side and two on the decimal side.
The hundredths digit is the sum of the tens and ones digit
Assume the ones digits as x
The tens digit is three times the ones digit
The tens digit is two times the tenths digit
Using the above clues, we get
The whole number side as [3x][x] and the decimal side as [3x/2] [x+3x]
The number becomes [3x][x].[3x/2][4x]
Since we know the number is less than a hundred, we use the trial and error method.
Let x = 1, and then the number becomes
31.[3/2]4 (this scenario is not possible)
Let x = 2, and the number becomes
62.38
If x = 3, the number is
93.[9/2]12 (Not Possible)
Hence the correct answer is 62.38
