Answer:

I think your question is to find the value of x.

Here is the solution.

Marks in English = 36

Marks in Hindi = 44

Marks in Maths = 75

Marks in Science = x

Now, average marks = 50

⇒Total marks in 4 subjects /4 = 50

⇒36+44+75+x /4 = 50

⇒x = 200 − 155 = 45

Marks obtained in Science = 45
