Gce Model Questions Vol1 2017 Commerce Question 35

A company wants to improve internal communication and is considering three methods: 1. Weekly face‑to‑face meetings lasting 2 hours. Attendance is 80 % of the 50 employees, and each attending employee saves 15 minutes of work per week because of clearer instructions. 2. Daily email updates that take 5 minutes to read per employee but save 8 minutes of other work per day. 3. An intranet portal costing ₦500,000 to develop and ₦50,000 per year to maintain, which saves 10 minutes of work per employee each working day (260 days per year). The cost of employee time is ₦2 500 per hour. Using both meetings and email together reduces the time saved by meetings by 20 % due to overlapping information; the intranet savings are independent of the other methods. The company's total annual budget for communication improvements is ₦1 200,000. Determine which combination of the three methods yields the greatest net monetary benefit (total value of time saved minus total cost) while staying within the budget. State the selected methods and the net monetary benefit (in naira).
