Question

300 oranges are distributed among the students of a class. Each student gets oranges three times the number of students present in the class. The number of students in the class was _____.
1. 20
2. 10
3. 18
4. 15

Answer 1

Correct Answer - Option 2 : 10

Given:

Total number of oranges = 300

Number of oranges got by a student = 3 × Number of students

Calculation:

Let the number of students be n 

Number of oranges got by each student = 300/n

Now, According to the question 

300/n = 3n

⇒ n² = 300/3

⇒ n2 = 100

⇒ n2 = 10²

⇒ n = 10

∴ The number of students by 10.
