Question

How do you increase 300 by 4%?

Answer 1

`104%=312`

Explanation:

Well to start off, with any given number we can say it is `100%`.

`therefore` `300=100%`

Therefore, we can find out that if we divide by `100`, we can get `1%`

`300=100% -> 3=1%`

Therefore we can figure out `4% = 4 xx 1%`, therefore we multiply the value of `1%` by `4`

`4%=4 xx 1% -> 4xx3=12`

`therefore` `4%=12`

But we want an INCREASE in `4%` therefore we add this on.

`104%=300+12 -> 312`

`104%=312`

Answer 2

`312`

Explanation:

method 1

find `4%` of `300` then add

`4%rarr4/100xx300=12`

`:. " increased amount "=300+12=312`

method 2

multiply by `1+4/100=1.04`

`300xx1.04= 312`
