correct answer is: d) 1.92 kg

Explanation

1 packet of sugar weight is 2.84 kg
\therefore 12 packets of sugar weight are =\left(2.84\times12\right) kg
\rightarrow\large\left(\frac{284\times12}{100}\right) kg _{[remove decimal]}
\rightarrow34.08 kg
According to the question,
The total weight of box along with the packets is 36 kg
\therefore The weight of box is =\left(36-34.08\right) kg
\rightarrow\left(36-\large\frac{3408}{100}\right) kg
\rightarrow\large\left(\frac{3600-3408}{100}\right) kg
\rightarrow\large\frac{192}{100} kg
\rightarrow1.92 kg
Ans: The weight of box is 1.92 kg.

There’s another way to pose this same question:
1. Find the weight of the box containing 12 packets of sugar, given that each packet weighs 2.84 kg and the total weight of the box with packets is 36 kg.
2. What is the weight of the box holding 12 sugar packets, with each packet weighing 2.84 kg, given that the total weight of the box and packets is 36 kg?
3. Calculate the weight of the box when there are 12 packets of sugar inside, each weighing 2.84 kg, and the total weight of the box and packets is 36 kg.
