A telephone poll asked people whether they like playing golf. Of the 100 people polled,20 like playing golf. What percentage of the people like playing golf?

Given:

Of the 100 people polled, 20 like playing golf.

To find:

The percentage of the people who like playing golf.

Solution:

In the poll,

Total number people = 100

Who like playing golf = 20

Now, percentage of the people who like playing golf is

Therefore, 20% of the people like playing golf.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

25% is the answer
