Answer 2

Heya !!!

This is your answer.....
It is given that 50% of total students got first grade and they are 12 in number.

Let the total number of students be x.

So, according to the question,

50% of x is 12.

So,

$x \times \frac{50}{100} = 12 \\ = > x = 12 \times 2 \\ = 24$
Hence the total number of students is 24.

hope you got the answer
