In a certain class, a teacher distributed a few candies and a few bars...

Given: Each student gets an equal number of candies and an equal number of few bars

Do not assume! Number of candies = Number of bars

To find out: The number of students in the class

Statement 1:

We know that each student received an equal number of candies and an equal number of bars.

Thus, the GCD of the number of candies and the number of bars is the largest possible number of students in the class.

180 = 2² × 3² × 5

40 = 2³× 5

The terms common to both: 2² 5 = 20
⇒ GCD of 40 and 180 = 20

Thus, the number of students could be 20 or a factor of 20 (that is, 1, 2, 4, 5, 10):

Scenario #1

Number of students = 20 (Maximum possible number of students):

Number of candies received by each student: 180 / 20 = 9
Number of bars received by each student: 4 / 20 = 2

Scenario #2

Number of students = 10

Number of candies received by each student: 180 / 10 = 18
Number of bars received by each student: 40 / 10 = 4

Scenario #3

Number of students = 5

Number of candies received by each student: 180 / 5 = 36
Number of bars received by each student: 40 / 5 = 8

There are three more possible cases for the number of students, i.e. 4 or 2 or 1. Of these, the possibility of the number of students being 1 can be rejected because the question explicitly mentions students in the plural.

So, the number of students can be 20, 10, 5, 4, or 2.

Thus, there is no unique answer. – Insufficient

Statement 2:

There is no information about the number of candies and the number of bars distributed. – Insufficient

Statement 1 & 2 together:

Combining both statements, we find that since the total number of items received by each student is less than 20, the only possible scenario is Scenario #1, where:
i. the number of students is 20.
ii. Total number of items received by each student: 9 + 2 = 11< 20.
The total number of items received by each student in other scenarios is more than 20. – Therefore, we’ve arrived at a unique answer: the number of students is 20. Sufficient
