Question

As of 2016, there were 118 known elements. These elements can be described with 10 classifications as summarized in the given table.

The percentage of the 10 classifications that have 11 or more elements is $p straight percent sign$ . What is the value of p ?

The correct answer is: P = 40

HINT :- Find the percentage of the 10 classifications that have 11 or more elements from the table and compare it p% to get p.
Explanation :
The percentage of the 10 classifications that have 11 or more elements is
$fraction numerator left parenthesis n o. o f space c l a s s i f i c a t i o n s space t h a t space h a v e space 11 space o r space m o r e space e l e m e n t s right parenthesis over denominator left parenthesis t o t a l space c l a s s i f i c a t i o n s right parenthesis space cross times space 100 percent sign. end fraction$
Step 1: finding no. of classifications that have 11 or more elements
no. of classifications that have 11 or more elements = 4( i. e 15,15,38,11)
Step 2 :finding total no. of classifications
Total no. of classifications = 10 (given)
The percentage of 10 classifications that have 11 or more elements is = $4 over 10$ x100 %
= 40 %
p%= 40%
So ,p= 40.
