question not clear (Question: 181193.1 )

1.you didn't give how many marks deduction for wrong and award for right.
2. if we take 1 for each right and wrong question. the in statement gave 10 wrong so 10 questions wrong and there also that 10 question 30% so total 33 question. so we can find total no question. so we can find by both..

Question:
DIRECTIONS: In each of the following questions, a question is followed by information given in two statements. You have to study the question along with the statements and decide, the information given in which of the statements (s) is necessary to answer the question?

In an exam that Debjit took, marks were awarded for correct answers, and deducted for wrong answers. No marks were awarded or deducted for unattempted questions. The qualifying mark was 25%. Did Debjit qualify?


I. He scored 46 from all his correct answers.

II. He went wrong in 30% of the total number of problems because of which 10 marks were deducted from his score.

Options:
A)

If the question can be answered by using statement I alone but not by using statement II alone

B) If the question can be answered by using statement II alone but not by using statement I alone
C) If the question can be answered by using either of the statements alone
D) If the question can be answered by using both the statements together but not by either of the statements alone
E) If the question cannot be answered even by using both the statements together
Solution:
Ans: (e) From I, as we only know the marks obtained by Debjit from his correct answers, we cannot determine whether he qualified, as we do not know the total marks in the exam. Statement I alone is insufficient.

From II, as we do not know the number of correct answers, we can not find the answer. Statement 11 alone is insufficient.

Combining the two the statements, we have Debjit’s net score as 46 – 10 = 36. But we don’t know what percentage of the total marks is 36. Even by combining the two statements, we cannot find the answer.
