In rounding off numbers, the last figure kept should be unchanged if the first figure dropped is less than 5.
Example: If only one decimal is to be kept, then 6.422 becomes 6.4.

Can you explain the answer of this question below:After decimal point,...
The correct answer is option 'C': The retained number remains unchanged.
Explanation:
When we have a decimal number and need to round it to a certain place value, we look at the digit immediately to the right of that place value. If the digit is less than 5, we ignore it and keep the digits to the left unchanged. This is known as rounding down or truncating the number.
For example, let's consider the number 3.14159. If we want to round it to two decimal places, we look at the digit in the third decimal place, which is 1. Since 1 is less than 5, we ignore it and keep the digits to the left unchanged. Therefore, the rounded number is 3.14.
Similarly, if we have the number 2.349, and we want to round it to the nearest whole number, we look at the digit immediately to the right of the decimal point, which is 3. Since 3 is less than 5, we ignore it and keep the digit to the left unchanged. Therefore, the rounded number is 2.
In both of these examples, the retained number remains unchanged because the digit to the right of the decimal place is less than 5.
It's important to note that if the digit to the right of the decimal place is 5 or greater, then the retained number will increase by 1. This is known as rounding up. However, in the given scenario where the digit is less than 5, the retained number remains the same.
In summary, when the digit to the right of the decimal place is less than 5, the retained number remains unchanged.
