Lecture # 21 - 28

DON’T MISS THESE Important instructions:

• There are 4 questions in the assignment but only one question will be graded. However we are not mentioning that which question will be graded so you have to provide the solution of all 4 questions.

In case the student has not solved that question which is set to be 
marked, he/she will be graded zero marks. For example if it is decided at 
instructor’s end that question # 2 is set for marking and student has solved 
other questions but not question # 2 then marks awarded will be zero. So 
students have to provide solution of all 4 questions.

• Upload assignments properly through LMS only, (No Assignment will be accepted through email).
• All students are directed to use the font and style of text as is used in this document.
