Multiplication with Three! Adding the Resultant Digits!

One of the amazing concepts associated with the numbers is multiplication with three and adding the resultant digits.

As per this amazing concept, if any number is multiplied with three and the resultant digits are added all together, then the new resultant digits are divisible by three.

The Concept

Step 1: Take any number.

Step 2: Multiply the number (taken in Step 1) with three.

Step 3: Add the resultant digits (obtained in Step 2) all together.

Step 4: The new resultant formed in Step 3 is divisible by three.

For Example

Number 15

Multiply the number with three: 15 x 3 => 45.

Add the resultant digits: 4 + 5 => 9.

The new resultant is divisible by three: 9 / 3 => 3.

Number 25

Multiply the number with three: 25 x 3 => 75.

Add the resultant digits: 7 + 5 => 12.

The new resultant is divisible by three: 12 / 3 => 4.

Number 99

Multiply the number with three: 99 x 3 => 297.

Add the resultant digits: 2 + 9 + 7 => 18.

The new resultant is divisible by three: 18 / 3 => 6.

Number 199

Multiply the number with three: 199 x 3 => 597.

Add the resultant digits: 5 + 9 + 7 => 21.

The new resultant is divisible by three: 21 / 3 => 7.

Number 999

Multiply the number with three: 999 x 3 => 2997.

Add the resultant digits: 2 + 9 + 9 + 7 => 27.

The new resultant is divisible by three: 27 / 3 => 9.

Hope you have understood this amazing concept of multiplication with three and adding the resultant digits. You can try yourself using any other number. In case of any issue, provide your valuable comments.
