A number is divided by 6 and gives a remainder of 4. If this number is multiplied by 3, what will be the remainder when the result is divided by 6?

A number is divided by 6 and gives a remainder of 4. If this number is multiplied by 3, what will be the remainder when the result is divided by 6?

Step 1: Understand that when a number is divided by 6 and gives a remainder of 4, it can be expressed as 6k + 4, where k is any whole number.
Step 2: Multiply the expression 6k + 4 by 3. This gives us 3(6k + 4).
Step 3: Distribute the 3 in the expression: 3(6k) + 3(4) = 18k + 12.
Step 4: Now, we need to find the remainder when 18k + 12 is divided by 6.
Step 5: Notice that 18k is divisible by 6, so it gives a remainder of 0.
Step 6: Next, divide 12 by 6. The remainder is also 0.
Step 7: Combine the remainders: 0 (from 18k) + 0 (from 12) = 0.
Step 8: Therefore, the final remainder when the result is divided by 6 is 0.
