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 = ? Correct Answer 31680 grams

  Box   :   Paper bundle
Weight   3 : 22
Let 3x : 22x
Total weight = 3x + 22x = 25x
25x = 36kg
$$\eqalign{ & x = \frac{{36}}{{25}} \times 1000 \cr & \,\,\,\,\, = 1440{\text{ grams}} \cr} $$
(∴ 1 kg = 1000 grams)
∴ Weight of paper bundles = 22x
= 22 × 1440 grams
= 31680 grams
