78 students, which is 30% of the whole class. What is the total number of students in the class?

200

260

320

280

We are given that 78 students represent 30% of the total number of students in the class.

Let's find the total number of students (X).

Using the percentage formula:

$30/10 0 \times X = 78$ $X = frac{78 times 100}{30}$ $X = frac{7800}{30} = 260$

So, the total number of students in the class is 260
