Question

How many people will participate in today's contest?

Answer 1

According to me the answer is 70

Here we are assuming the probability of the students participating in the contest

because there is no exact answer to this question.

But we may assume that

x number is the total population.

y is the number of people who are not participating

Therefore x-y = a

Therefore a will be the exact number of people participating in the contest.

For example

x= 100 students in a class

y= 30 non participating students

Therefore the correct answer would be

a (number of students participating in the contest)= x-y = 100-30= 70

Therefore the correct answer would be 70 students

Answer 2

The number of the people who will participate in the contest will be more than 50.

Explanation:

• As there are 10 teams who are taking part in the quiz contest.
• Each team was allowed to select 5 people and make a group.
• As each team has 5 contestants and there are total 10 teams in this contest:

                      10 x 5 = 50

• Thus, 50 people will participate in the contest.
