In Grade 8, 10 students liked juice. In Grade 8, 40% of students liked milk shake. In Grade 9, 47% of students liked cola. In Grade 9, 53 students liked cola.

Answer 1

In grade 8, 40% of the students liked milk shakes

Answer 2

In Grade 8, 40% of the students liked milkshake - is the correct option

Explanation:

We are given the table representing the relative frequency of the favorite drinks of students in different grades.

Since from the table, we see that,

The percent of students in grade 8 who like juice = 0.1% = 10%

So, option 1 is not correct.

The percent of students in grade 8 who like milkshake = 0.4% = 40%

Thus, option 2 is correct.

The percent of students in grade 9 who like cola = 0.53% = 53%

So, option 3 and 4 are not correct.

Hence, we get that the correct option is,

In Grade 8, 40% of the students liked milkshake.
