Show Answer
Answer:
Correct Answer: D
Solution:
- Ratio of weight of box and paper bundles $ =3:22 $ Weight of the book $ =3xg $ Weight of the bundles $ =22,x,g $
$ \therefore $ $ 3x+22x=36\times 1000g $
$ \Rightarrow $ $ 25x=36000 $
$ \Rightarrow $ $ x=\frac{36000}{25}=1440g $ Weight of the paper $ =22\times 1440=31680g $ Alternate Method Weight of paper bundles $ =\frac{a}{a+b}\times p $ where, p = Total weight and a, b-are individual weights
$ \therefore $ Weight $ =\frac{22}{25}\times 36kg=\frac{22\times 36\times 100}{25}=31680g $
