Best answer
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

⇒ 2x= 800

⇒ x= 800/2

⇒ x= 400

⇒ x = √400 

⇒ x = 20 

∴ The number of students in the class are 20.
