in an examination a student who scores 35% marks fails by 60 marks while another scores 52% marks got 8 marks more than the passing requirement the passing marks are
Answers
This Can be solved algebraically as follows…
We assume total marks = x
1st Candidate scores 30% of x = 3x/10
Fails by 5 marks
So, minimum pass marks=( 3x/10) + 5
= (3x + 50) /10 …………(1)
2nd candidate scores 40% of x = 4x/10
He svores 10 more than minimum
=> minimum pass marks = (4x/10) - 10
= (4x-100) / 10 …………. (2)
(1)&(2) are eaqual
=> (3x+ 50)/10 = (4x- 100) / 10
=> 3x + 50 = 4x - 100
=> x = 150
=> minimum pass marks by (1)
=( 3x+50)/10
= (3 x 150 + 50) /10
=> 500/10
= 50 marks out of 150 is required to pass
So minimum pass percentage =
(50/ 150) x 100
= 100/3
= 33.3 %
ONLY AN EXAMPLE OR SIMILAR ANSWER !!1
Answer:
Let passing marks be P.
Also, let full marks be F.
Then,
35F/100 + 60 = P ----------(i)
And,
52F/100 = P + 8 --------(ii)
Subtracting (i) from (ii) :-
17F/100 - 60 = 8
17F/100 = 68
F = 68×100/17 = 400
Therefore, P = 35×400/100 + 60 = 140 + 60 = 200
