To solve this problem, let's assume the original number as 'x'.
1. Multiplication and Addition:
The number is multiplied by 5, so the result becomes 5x. Then, 25 is added to it, making it 5x + 25.
2. Division and Subtraction:
The result obtained from step 1 is divided by 5, so we get (5x + 25) / 5. Now, we subtract the original number 'x' from this result. Thus, the final expression becomes (5x + 25) / 5 - x.
3. Simplifying the Expression:
To simplify this expression, let's first distribute the division operation over the subtraction.
(5x + 25) / 5 - x = (5x + 25) / 5 - (5x / 5) = (5x + 25) / 5 - x = (5x + 25 - 5x) / 5 - x = 25 / 5 - x = 5 - x
4. Finding the Remainder:
Now, we have the expression 5 - x. To find the remainder, we substitute 'x' with different values and see which one satisfies the condition.
If we substitute x = 5, then the expression becomes 5 - 5 = 0, which is not the remainder mentioned in the options.
If we substitute x = 0, then the expression becomes 5 - 0 = 5, which matches with the option C.
Therefore, when the original number 'x' is equal to 0, the remainder is 5. Hence, the correct answer is option C.
1. Multiplication and Addition:
The number is multiplied by 5, so the result becomes 5x. Then, 25 is added to it, making it 5x + 25.
2. Division and Subtraction:
The result obtained from step 1 is divided by 5, so we get (5x + 25) / 5. Now, we subtract the original number 'x' from this result. Thus, the final expression becomes (5x + 25) / 5 - x.
3. Simplifying the Expression:
To simplify this expression, let's first distribute the division operation over the subtraction.
(5x + 25) / 5 - x = (5x + 25) / 5 - (5x / 5) = (5x + 25) / 5 - x = (5x + 25 - 5x) / 5 - x = 25 / 5 - x = 5 - x
4. Finding the Remainder:
Now, we have the expression 5 - x. To find the remainder, we substitute 'x' with different values and see which one satisfies the condition.
If we substitute x = 5, then the expression becomes 5 - 5 = 0, which is not the remainder mentioned in the options.
If we substitute x = 0, then the expression becomes 5 - 0 = 5, which matches with the option C.
Therefore, when the original number 'x' is equal to 0, the remainder is 5. Hence, the correct answer is option C.
