The activity detnils and their predocessors are gaven below along with their activity times. Constroct the network diagram (1 Mark). Find out the critical path (0.5 Mark) and project duration (0.5 Mark)? The activity details and their predecessors are given below use the PERT method to calculate the expected tima (1 Mark) and construct the notwork diagran (1 Mark) to find the critical path of the activity (1 Mark) also indicate the projact duration (1 Mark) with the standard deviation (1 Mark). Question 4 Fag evertion Wet yot onswered A survey was conducted to study the relationship between expenditure on accommodation (X) and expenditure on Food and Entertainment ( Y ) and the following results were obtained. Find a regression equation between expenditure on accommodation and expenditure on Food and Entertainment (1 Mark). Then use the regression equation to find the expenditure on accommodation for 90 OMR (1 Mark) and for 200 OMR (1 Mark). \begin{tabular}{|l|l|} \hline \begin{tabular}{l} Expenditure \\ on accommodationexpenditure \\ (OMR) \end{tabular} & \begin{tabular}{l} Food \\ Entertainment \\ (OMR) \end{tabular} \\ \hline 124 & 117.5 \\ \hline 175 & 82.5 \\ \hline 264 & 78.5 \\ \hline 148 & 50 \\ \hline 272 & 92 \\ \hline 166 & 80 \\ \hline 172 & 89 \\ \hline 175 & 82.5 \\ \hline 158 & 52.5 \\ \hline \end{tabular} Enter the average expenditure on accommodation : Enter the average expenditure on Food and Entertainment : Enter the equation constant b value: Enter the equation constant a value: Enter the expenditure on accommodation for OMR 90 : Enter the expenditure on accommodation for OMR 200 : Demand for the Child Cycle at Best Buy is 2375 units per month. Best Buy incurs a fued order placement, transportation, and receiving cost of 5550 each time an order is placed. Each cycle costs 500 and the retaler has a holding cost of 33 \%. Cakculate: A) Inwentory carrying cost. B) Economic Ordering Quantity. c) Optimum order interval in days. D) Averapa imventory at any time. E) storage cost at any time. F) Minimum total inventory cost per year. Question 6 ABC Ltd. uses EOQ logic to determine the order quantily for its varous components and is planning its orders. The Annual consumption is ga200 units, Cost to place one order is 1025, Cost per unit is 63 and carrying cost is 8.5% of Unit cost. Caculate: A) inventory carrying cost. B) Fconemic Ordering Quentity. c) Optimum order interval in days. D) Averege imventery at any time. E) storage cosi at any time. F) Minimum total imventory cost per year
