    Post TestFunda Answers - Higher Maths

     In a competitive exam, there were 75 questions, where 4 marks were awarded for every correct answer and 1 mark was deducted for every wrong answer. No marks were awarded/deducted for unattempted questions.

    If 1000 students wrote the exam, what is the minimum possible number of students each of whose net score is the same as that of at least one of the other students?

    Options
    1) 
    630
    2) 
     730
    3) 
     731
    4) 
    631
    5) 
    None of these

    Sum of their marks = 358
    By statement 1, Ram got 175 marks
    now, 358/2 = 179
    If one of them had got 179 or more, we could have said that he has got the highest marks. But since 175< 179, Ram could still come second if Rahul or Raghav scores greater than 175
    So, we cannot conclude anything from the first statement alone
    By statement 2, Rahul got 119 marks
    So, it is decided that Raghav gets 358 - (175+119) =  64
    So, Ram gets the highest marks
    Hence, option 3 is correct

    the possible scores are -75,-74.......0,1,2,3.........288,290,291,292,295,296,300
    total 370
    assuming 370 students have different scores then min no of students that can have same score is 1000-370=630

    (n-5)A=B(5n-1)

    n=12, 14 and 16 give 5n-1 as very high primes of non primes with high prime factors

    hence n =21
