Answer: d. 25

Step-by-step explanation:

Let x be the total number of students in the class.

As per given :

Number of students want ice cream party = 20% of x= 0.20x

[we divide percent by 100 to convert it into decimal.]

Actual number of students want ice cream party =5

⇒  0.20x=5

Divide both sides by 0.20 , we get

⇒ x=  [tex]\dfrac{5}{0.20}=\dfrac{500}{20}=25[/tex]

Hence, the total number of students in the class.= 25

Thus , the correct answer is d. 25
