Show answer & explanation
Correct answer: C
Concept
To express one total as a percentage of another, divide the first total by the second and multiply by 100. When several days are combined, add their values before forming the ratio.
Application
Shop A total for Thursday and Friday: 720 + 840 = 1,560 HDDs.
Shop B total for Wednesday and Thursday: 540 + 760 = 1,300 HDDs.
Required percentage = (1,560 ÷ 1,300) × 100 = 1.2 × 100 = 120%.
Cross-check
Since 1,560 is 1.2 times 1,300, the first total is 120% of the second total. Therefore, the result is 120%.
