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%.
