A box filled with paper bundles weights 36kg. If the weight of the box and paper bundles respectively are in the ratio of 3 : 22 then the weight of the papers (in grams) is = ?

Answer: Option D

	Box	:	Paper bundle
Weight	3	:	22
Let	3x	:	22x

Total weight = 3x + 22x = 25x
25x = 36kg
$$\begin{array}{rl}& x=\frac{36}{25}\times 1000\\ & =1440\text{ grams}\end{array}$$
(∴ 1 kg = 1000 grams)
∴ Weight of paper bundles = 22x
= 22 × 1440 grams
= 31680 grams
