Detailed Explanation & Answer
Total number of HDDs purchased by males from Shop A on Tuesday and Wednesday together:
= (100% - 45%) of 560 + (100% - 40%) of 720
= (0.55 × 560) + (0.60 × 720)
= 308 + 432
= 740
Total number of HDDs purchased by females from Shop B on Thursday and Friday together:
= (25% of 760) + (40% of 550)
= (0.25 × 760) + (0.40 × 550)
= 190 + 220
= 410
