Answer:
(1) 6%; 1.7; 10.20%
(2) 3%; 4; 12%
Explanation:
ROI = Margin × Turnover (Note Margin in % and Turnover in Ratio)
Where,
Margin = Net operating income ÷ Sales
Turnover = Sales ÷ Average operating assets
For Queensland:
Margin = 54,060 ÷ 901,000
= 6% (approx)
Turnover = 901,000 ÷ 530,000
= 1.7
ROI = 6% × 1.7
= 10.20%
For New south wales:
Margin = 74,400 ÷ 2,480,000
= 3% (approx)
Turnover = 2,480,000 ÷ 6,20,000
= 4
ROI = 3% × 4
= 12%
