C
$$48 manuals * \frac{400 grams}{1 manual} * \frac{1 kg}{1,000 grams}$$

Solution

Given:

To find:
• The weight of 48 manual, in kilograms

Approach and Working:
• The weight of 48 manuals = 48 * 400 grams = 19200 grams = 19.2 kilograms

Hence, the correct answer is option C.

400 grams=400/1000=0.4 kg
48 manuals * 0.4 kg= 19.2 kg

Pretty straightforward, I think:

48*400 = 19200 grams

19200 * (1/1000) --> (19200/1000) --> (192/10) --> 19.2

One box weighs (48 x 400)/1000 = 48 x 0.4 = 19.2 kilograms.

IMO C
