Answer: c) 71 and 63
Explanation:
Country ratings based on weight and ratings scale;
Taiwan
= (0.15*85 + 0.15*85 + 0.2*70 + 0.1*85 + 0.4*30)
= (12.75 + 12.75 + 14 + 8.5 + 12)
= 60
Thailand
= (0.15*95 + 0.15*20 + 0.2*65 + 0.1*50 + 0.4*70)
= (14.25 + 3 + 13 + 5 + 28)
= 63.25
Singapore
= (0.15*40 + 0.15*95 + 0.2*75 + 0.1*85 + 0.4*70)
= (6 + 14.25 + 15 + 8.5 + 28)
= 71.75
Vietnam
= (0.15*30 + 0.15*20 + 0.2*55 + 0.1*50 + 0.4*60)
= 4.5 + 3 + 11 + 5 + 24
= 47.5
Best options would be Singapore followed by Thailand
