Q: Which vendor is among the top two vendors in exactly three aspects?

Correct Answer: Option C (Vendor 4). Top 2 for Cost: V3(90), V5(85). Quality: V4(90), V1(80). Reach: V3(85), V5(80). Reliability: V4(85), V5(80). Service: V1(90), V2(85). Features: V4(90), V5(85). Counting appearances: V1 (2), V2 (1), V3 (2), V4 (3), V5 (4). Vendor 4 appears exactly three times.

Q: If a composite score is calculated as (0.3 * Quality + 0.2 * Reliability + 0.5 * Cost), which vendor has the highest composite score?

Correct Answer: Option D (Vendor 5). V1: 0.3(80) + 0.2(55) + 0.5(75) = 24 + 11 + 37.5 = 72.5. V3: 0.3(60) + 0.2(70) + 0.5(90) = 18 + 14 + 45 = 77. V4: 0.3(90) + 0.2(85) + 0.5(60) = 27 + 17 + 30 = 74. V5: 0.3(75) + 0.2(80) + 0.5(85) = 22.5 + 16 + 42.5 = 81. Vendor 5 is the highest.

Q: What is the absolute difference between the average score of Vendor 5 and Vendor 1 across all six aspects?

Correct Answer: Option C (7.5). V5 average = (85+75+80+80+70+85) / 6 = 475 / 6 = 79.16. V1 average = (75+80+60+55+90+70) / 6 = 430 / 6 = 71.66. Difference = (475 - 430) / 6 = 45 / 6 = 7.5.

Q: Which aspect has the lowest average score across all five vendors?

Correct Answer: Option A (Reliability). Sum of Cost = 390 (avg 78). Quality = 375 (avg 75). Reach = 370 (avg 74). Reliability = 355 (avg 71). Service = 385 (avg 77). Features = 385 (avg 77). Reliability has the lowest average at 71.

Q: If Vendor 2's Features score was improved by 25% and its Reach score dropped by 20%, what would be its new average score across all 6 aspects?

Correct Answer: Option C (76.66). Current Features = 80. +25% = 100 (+20). Current Reach = 75. -20% = 60 (-15). Net change = +5. Current total for V2 = 80+70+75+65+85+80 = 455. New total = 460. New average = 460 / 6 = 76.66.
