Answer 1

The answer is D.

Explanation:

First, you have to find the differences in number of guests in this 2 party :

`31 - 20 = 11 \: guests`

Next, you have to divide by the smaller value which is the first party, then, multiply by 100 as the question wants percentage increase :

`(11)/(20) * 100 = 55\%`
