Answer #1

Given :-

suppose there are 10 numbers in the list.
n = 10
10% of the number in the list are 15.
There is only one 15
20% of the numbers are 25.
So, there are two 25.
Remaining 70% of the numbers are 50.
So, there are seven 50.
So, data can be written as,
15,25,25,50,50,50,50,50,50,50
Our aim is to find average of this data.
Average = sum of observations / no.of the observations.
= 15+25+25+50+50+50+50+50+50+50 / 10

= 415/10

= 41.5

Average of the numbers in the list is 41.5
