Tr-Top 27-26 0.577, for which z Value = 0.2190 (given) 1.732 So, Prob of completing within 27 weeks-0.5 NT(Z) -0.5.0.2190 - 71.90% So, Probability of not completing within 27 weeks = 100% - 71.90% = 28.10% Probability 0.9 -0.5 + NT(Z).

The rate is 60 per Machine Hour. The Company has analysed its operations and determined that five activities act as Cost Drivers for Overheads. Data relating to five activities are given below: 30 0.50 16% 14% P Q R Gurukripa's Guideline Answers for Nov 2017 CA Final Advanced Management Accounting Exam Activity Area Cost Driver Cost of each activity as % of Total Production Overhead Cost Store Receiving Number of Requisitions 25% Machine Set-up Number of Set-ups 20% Machine Running Machine Hours worked 25% Packing Packing Time in Hours Storage Area in Square Metres The investigation into the Production Overhead Activities for the period revealed the following: Activity Number of Requisitions 1,200 1,500 3,900 Number of Machine Set-ups 120 320 Packing Hours 3,000 4,800 10,200 Storage (Sq metres) 10 800 12.000 19,200 Required: 1.
