Given:

Total people = 546

Number of Females= 412

Attendees under the age 15 = 96

Attendees between the ages 21 and 29 = 242

From the above information, we can easily calculate:

Number of males = Total - number of females= 546-412= 134

Now, we will check the options one by one.

A) Ratio of females to total peope is given by:


412\colon546

Hence, the statement is true.

B)Ratio of females to males is given by:


412\colon134

Hence, this statement is true.

C)Ratio of attendees under age 15 to attendees having ages between 21 to 29 is given by:


96\colon242

Hence, this statement is true.

D)According to given data,ratio of total to attendees having age over 65 is given by:


546\colon23

This does not match the given statement so it is not true,since, the ratio is not given in the correct order.

Therefore, option D is not true.
