**Hint:**Mass is commonly measured by how much something weighs. In the metric system of measurement, the most common units of mass are the gram and kilogram.

Rules of addition/ subtraction are as follows:

1. Write the numbers to be added/subtracted in vertical form.

2. While adding/subtracting units write them in separate columns, i.e., ‘kg’ and ‘g’ to be written in

separate columns.

3. Finally, adding/subtracting as usual.

To convert kilograms into grams, multiply the given measure in kilograms by 1000 and write the unit gram (g) after it.

$1kg = 1000g$

To convert the grams into kilograms and grams, the last 3 digits from the right represent the number of grams and the rest of the digits represent the number of kilograms. For eg:

7216 g = 7 kg 216 g

**Complete step by step solution:**We have to add the terms 17 kg, 13 kg 940 g and 15 kg 65 g

We will arrange all the terms into column and add them

Therefore, the sum is 45 kg 1005 g

Now, $1kg = 1000 g$ so we can convert 1005 g into kg

We can write 1005 g as

$\begin{gathered}

1005g = 1000g + 005g \\

1005g = 1kg + 5g \\

\therefore 1005g = 1kg5g \\

\end{gathered} $

Therefore, 45 kg 1005 g will be equal to 46 kg 5 g

Hence, the sum is 46 kg 5 g

∴Option (D) is correct

**Note:**1. To convert kilograms to grams we have to multiply the number of kilograms by 1000 and to convert grams to kilograms we divide the number of grams by 1000.
