विद्यार्थियों के औसत अंक 50 है तो कुल अंक
होंगे
O 5000
O 4000
O 3000
O None of these इनमें से कोई नहीं​

Answer 1

The correct option will be option (1).

The total marks will be 5000.

-------------------------------------------------------------------------------------

Let's understand a few concepts:

To calculate the total marks we will use the following formula for the average:

$\boxed{\bold{Average = \frac{Sum \:of\:observations}{Number\:of\:observations} }}$

-----------------------------------------------------------------------------------

Let's solve the given problem:

The number of students = 100

The average marks of 100 students = 50

Let's say "x" be the total marks.

Therefore, by using the above formula of average, we can form an equation as,

$50 = \frac{x}{100}$

$\implies x = 50 \times 100$

$\implies \bold{x = 5000}$

Thus, the total marks of 100 students will be 5000.
