The original 15 people are 10% of the total number of people who received the mail.
Step-by-step explanation:
Given,
Number of people who received mail = 15
Mail further sent to 3 more friends;
Number of people who received mail from 15 people = 15*3 = 45 people
Number of people who received mail from 45 people = 45*2 = 90 people
Total number of people = 15+45+90 = 150 people
Now,
Percent of original people = [tex]\frac{Number\ of\ original\ people}{Total\ number\ of\ people}*100[/tex]
Percent of original people = [tex]\frac{15}{150}*100=10\%[/tex]
The original 15 people are 10% of the total number of people who received the mail.
