| Directions: The following questions are accompanied by three statements I, II and III. You have to determine which statement(s) is/are sufficient/necessary to answer the given question. |
| I. Pratibha secured 42% marks in the examination and was declared failed by 10 marks. Shruti secured 45% marks in the examination and got 13 marks more than the minimum pass marks. |
| II. Pratibha secured 575 marks in 9 subjects. |
| III. A student will be declared passed if he secures 32.5% of the total marks. |
A) Only I and III
B) Only I and II
C) All together are necessary
D) Only I
E) Any two of them
Correct Answer: D
Solution :
From I. According to the question, \[42%+10=45%-13\] or,\[23=3%\] \[\therefore \]\[3%=23\] \[\therefore \]\[42%=\frac{23}{3}\times 42=322\] Pass marks\[=322+10=332\] Hence statement I alone is sufficient to answer the question. But II and III are not sufficient to answer the question because we need more information to find the pass marks.
