A scored mark = 30%

A Failed by = 15 marks

B scored = 40% 

Obtained marks = 35

Calculation : 

Let x be maximum marks

⇒ 30% x + 15 = 40% x - 35

⇒ 30% x - 40% x = - 35 - 15

⇒ -10% x = -50

⇒ x = (50×100)/10

⇒ x = 500 

Therefore, The maximum marks is 500.

The pass marks is expressed as shown below,

Pass marks  

⇒ [(30 × 500)/100] + 15

Pass marks = 165 

Therefore, the pass percentage is calculated as shown below,

Pass% = (165/500) × 100

∴ The pass percentage is 33%.
