Question
Questions 35 and 36 refer to the following information.
As of 2016, there were 118 known elements. These elements can be described with 10 classifications as summarized in the given table.
An element is a nonmetal if it is classified as a halogen, noble gas, or other nonmetal. The ratio of all nonmetals to all elements is 10 to k. What is the value of k?
The correct answer is: 59
The total elements = 7 + 7 + 6 + 7 + 6 + 6 + 15 + 15 + 38 + 11 = 118
The total halogens, noble gas or other metal = 7 + 6 + 7 = 20
Ratio = 20 : 118 10 : 59 = 10 : k
k = 59
