Wishing you good luck!
SECTION 1 (Maximum Marks: 24)
• This section contains EIGHT (08) questions.
• The answer to each question is a NUMERICAL VALUE.
• For each question, enter the correct numerical value of the answer using the mouse and the onscreen
virtual numeric keypad in the place designated to enter the answer. If the numerical value has more
than two decimal places, truncate/roundoff the value to TWO decimal places.
• Answer to each question will be evaluated according to the following marking scheme:
Full Marks : +3 ONLY if the correct numerical value is entered;
Zero Marks : 0 In all other cases.
