in an examination,a student requires 40% of the total marks to pass. if Ru pa gets 185 marks and fails by 15 marks,find the total marks?
0.4x = 200
x = 500
To find the total marks, we first need to determine what 40% of the total marks is.
Let's assume that the total marks are represented by 'x'.
The student requires 40% of 'x' to pass the examination. Therefore, 40% of 'x' is equal to 0.4x.
Given that Rupa gets 185 marks and fails by 15 marks, we can set up the equation:
0.4x = 185 + 15
Simplifying the equation:
0.4x = 200
Dividing both sides of the equation by 0.4:
x = 200 / 0.4
x = 500
Therefore, the total marks in the examination are 500.
