AI Explanation

To determine which test inputs would be selected using EQP, let's go through each option and calculate the postal rates for each weight:

Option A) 8, 42, 82, 102

  • For 8 grams: The postal rate is 25p.
  • For 42 grams: 35p + 10p = 45p.
  • For 82 grams: 35p + 10p + 10p + 10p = 65p.
  • For 102 grams: 35p + 10p + 10p + 10p + 10p + 10p = 85p.

Option B) 4, 15, 65, 92, 159

  • For 4 grams: The postal rate is 25p.
  • For 15 grams: The postal rate is 35p.
  • For 65 grams: 35p + 10p + 10p + 10p + 10p = 75p.
  • For 92 grams: 35p + 10p + 10p + 10p + 10p + 10p + 10p + 10p = 95p.
  • For 159 grams: 35p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p + 10p = 155p.

Option C) 10, 50, 75, 100

  • For 10 grams: The postal rate is 25p.
  • For 50 grams: 35p + 10p + 10p = 55p.
  • For 75 grams: 35p + 10p + 10p + 10p + 10p = 75p.
  • For 100 grams: 35p + 10p + 10p + 10p + 10p + 10p + 10p = 95p.

Option D) 5, 20, 40, 60, 80
