Question

800 chocolates were distributed among the students of a class. Each student got twice as many chocolates as the number of students in the class. The number of students in the class was:
1. 20
2. 35
3. 30
4. 25

Answer 1

Correct Answer - Option 1 : 20

Given:

Total number of chocolates for distribution = 800

Calculation:

let the number of students in the class = x

So the number of chocolates distributed among each student in the class = 2x

so according to question 

  Number of students × number of chocolates distributed among each student = total number of chocolate

⇒ x × 2x = 800

⇒ 2x² = 800

⇒ x2 = 800/2

⇒ x2 = 400

⇒ x = √400 

⇒ x = 20 

∴ The number of students in the class are 20.
