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 = $\frac{Number\ of\ original\ people}{Total\ number\ of\ people}*100$

Percent of original people = $\frac{15}{150}*100=10\%$

The original 15 people are 10% of the total number of people who received the mail.
