EOG Mathematics Standards — Questions and Answers
Question 1: A End of Grade professional needs to calculate a 15% increase on a base value of 240. What is the result?
- 276 (Correct answer)
- 255
- 288
- 264
Correct answer: 276
15% of 240 = 0.15 × 240 = 36. Adding this to the base: 240 + 36 = 276.
Question 2: In End of Grade, if a process has a completion rate of 85% and 340 items were started, how many were completed?
- 289 (Correct answer)
- 255
- 295
- 272
Correct answer: 289
85% of 340 = 0.85 × 340 = 289 items completed.
Question 3: A End of Grade report shows values of 42, 38, 45, 51, and 34. What is the mean (average)?
- 42 (Correct answer)
- 40
- 45
- 38
Correct answer: 42
Sum = 42 + 38 + 45 + 51 + 34 = 210. Mean = 210 ÷ 5 = 42.
Question 4: If a End of Grade project budget is $50,000 and actual spending is $57,500, what is the percentage over budget?
- 15% (Correct answer)
- 10%
- 12.5%
- 7.5%
Correct answer: 15%
Over budget amount = $57,500 - $50,000 = $7,500. Percentage = ($7,500 / $50,000) × 100 = 15%.
Question 5: In End of Grade, a ratio of 3:5 is used to divide 480 units. How many units are in the larger portion?
- 300 (Correct answer)
- 288
- 180
- 320
Correct answer: 300
Total parts = 3 + 5 = 8. Each part = 480 ÷ 8 = 60. Larger portion = 5 × 60 = 300.
Question 6: A End of Grade survey collected responses from 600 participants. If 72% responded positively, how many responded positively?
- 432 (Correct answer)
- 420
- 450
- 408
Correct answer: 432
72% of 600 = 0.72 × 600 = 432 positive responses.
