Answer 2

Given:

80% of students in a class of 50 students like to study Math.

To find:

The number of students who did not like to study Math.

Solution:

The correct option is A) 10.

To find the answer, we will follow the following steps:

As given, we have,

Total number of students in a class = 50

The percentage of students who like to study math = 80%

So, the percentage of students who did not like to study math

$= 100\% - 80\%$

$= 20\%$

Now,

The number of students who did not like to study math

$= 20\% \: of \: total \: students$

$= \frac{20}{100} \times 50$

$= 10$

Hence, the number of students who did not like to study math is A) 10.
