Given. Rahul attempted 125 problems and got 67 marks i.e.. he already lost 60 x 1/6 = 10 marks for unattempted questions and for every incorrect questions he loses another 4/3 (1 mark of the question and 1 /3rd negative marks) marks of this 115 marks.
125 - 10 - (4/3) (IN) = 67
F = 36
Total correct questions = 125 - 36 = 89
In DI, number of correct questions = 17 - 6 = 11
Net score =
Net score in Verbal = 12
Number of incorrect in LR = 6
Now, Sum of number of unattempted problems and correct questions in LR is 34 and as the total score in LR is an integer, the number of unattempted problems must be a multiple of 6.
By trial and error.
Number of unattempted problems =18
Number of attempted problems = 22
Number of correct questions =16
Net Score = 11
Number of incorrect in Verbal = 3
Net score = 12 By trial and error.
Number of unattemtped problems, which must be a multiple of 6 = 12
Number of correct questions =15
Now total correct questions = 89
∴ Number of correct questions in Quant =17
∴ Number of Incorrect = 12
∴Net score = 12
Number of incorrect in GK = 9
Number of unattempted problems in GK =6
T.P = Total Problems:
P.A = Problems Attempted:
S.A = Correct Questions"
IN = Incorrect:
NS = Net Score
Hence, the number of problems attempted by Rahul in Verbal is 18.
