A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many

Pani-rosa [81]

780 students prefer chocolate milk.

Step-by-step explanation:

Let,

the total percentage = 100%

Students who prefer plain white milk = 35%

Students who prefer chocolate milk = 100 - 35 = 65%

Number of students = 1200

No. of students who prefer chocolate milk = 65% of total students

No. of students who prefer chocolate milk = $\frac{65}{100}*1200$

No. of students who prefer chocolate milk = $\frac{78000}{100}\\$

No. of students who prefer chocolate milk = 780

780 students prefer chocolate milk.
