Question

A candidate attempted 12 questions and secured full marks in all of them. if he obtained 60% in the test and all questions carried equal marks, then what is the number of questions in the test?

Answer 1

Let The Number of question in the test = n 

question attempted by candidate = 12 

% marks obtained by candidate   = 60% 

ATQ 

60% of n = 12 

(60/100) n = 12 

n               = 12 . 100 / 60 

n               = 20 

So the test contained 20 questions 

Answer 2

Let The Number of question in the test = n 

question attempted by candidate = 12 

% marks obtained by candidate   = 60%  

60% of n = 12 

(60/100) n = 12 

n= 12 . 100 / 60 , n= 20 

So the test contained 20 question
