Candidate Question

A candidate who gets 20% mark
in examination fails by 30
marks out another
candidate who gets 32%
gets 42 marks more than
the pass marks Then the
percentage of pass mark is​

Answer 1

$\huge\blue{Solution}$

=>let the marks Max marks = x

=> according to the question,

(case 1) Pass mark = 20x/100 +30

(case 2) pass mark = 32x/100 - 42

Note :- pass marks be same in the both cases.

=> 20x/100 +30 = 32x/100 - 42

=> 32x/100 - 20x/100 = -42-30

( we are taking 32x/100 to another side and +30 to another side)

=>12x/100 = 12

=>(simplest form)

=>3x/25 =12

=> 3x = 12 X 25

=> 3x = 300

=> x= 300/3

=> x= 100

pass mark = 100 X 20/100 + 30

Passing mark = 50

Required percentage

=50/100 X100

=50%
