A candidate scores 20% marks and fails by 60 marks. Another candidate scores 32% marks and
84 marks more than the required number of marks to pass. Find the total number of marks and also
percentage of marks required to pass the examination.
​

Answer 1

Answer:

Step-by-step explanation:

By making the problem as an equation

20% of whole mark +30 marks = Pass mark

32% of the  whole mark - 42 marks = Pass mark

Bu equating, 12 % =72 mark , So 100 % = 600 marks(whole mark)

Pass mark =

600*(32/100) - 42 = 150

or

600 *(20/100) +30 =150

150 marks = 25 %

Answer 2

Answer:

25% is the required percentage to pass the exam
