ans FIVEquestions, taking ANY1WOfrom Group A,
ANY1WO[rom Group B and ALLfrom Group C.
AD parts of a ques. (a, b, etc) should be answered at 1 place.
ans should be bridand to-the-point and be supplemented with neat sketches. Unnecessary long answers may outcome in loss of marks.
Any mis~ing data or wrong data may be presumed suitably giving proper justification. Figures on the right-hand ~ide margin indicate lull marks.
