Nivaar worked solution (AI-drafted; not reviewed by a licensed engineer)
National Exams — May 2018 — 98-Ind-A2 Analysis and Design of Work. Three-hour, closed-book exam (approved Casio/Sharp calculator only); any five of the seven questions constitute a complete paper and only the first five answered in the answer book are marked — all seven are solved below for completeness. The source’s marking-scheme line for Question 3 mislabels its final sub-part “(ii)” a second time instead of “(iii)”; it is answered here in the natural (i)/(ii)/(iii) order that matches the question text itself, 5/5/10 marks.
