Answer:

The approximate passing percentage is 33%.

Step-by-step explanation:

Let x= maximum marks

30% x+ 15 = 40% x -35

30% x- 40%x = -35-15

-10% x = -50

x= (50x100)/10

x=500

Therefore, the maximum marks is 500.

The pass mark is expressed as shown below,

Pass marks = [(30 x 500)/100] + 15

Pass marks = 165

Therefore, the pass percentage is calculated as shown below,

Pass % = (165/500) x 100

Pass Percentage = 33%
