Neco Model Questions Vol1 2019 Geography Question 17

A manufacturing firm is choosing a location for a new factory. Three sites (A, B, C) are evaluated on three cost criteria: transport cost (₦ per ton·km), labour cost (₦ per worker per month) and power cost (₦ per kWh). The decision‑making weights are 0.5 for transport, 0.3 for labour and 0.2 for power (lower cost is preferred). The data are: - Site A: transport 0.08, labour 45 000, power 12\n- Site B: transport 0.06, labour 48 000, power 10\n- Site C: transport 0.07, labour 44 000, power 13 Using the factor‑rating method with normalisation (the lowest cost for each criterion receives a normalised value of 1, other sites receive lowest / their cost), compute the weighted score for each site and state which site should be selected.
