Answer 1

Answer 2

These types of questions are proportion questions and are quite simple to solve. We just need to ask ourselves a question like the one below;

• If we have a
  `6` pounds package and it increases by
  `2` pounds, how many pounds will it increase in a
  `100` pound package?

`6P > +2P\\100P > (?)P`

We should do cross-multiplication.

1. 
   `(100P)(2P)=(6P)(?P)`
2. 
   `(200)P=(6?)P`
3. 
   `200=6?`
4. 
   `(200)/(6) =?`

Result: Option D, %
`33,3`
