- A45
- B36Correct
- C24
- D360
Why: To find 15% of 240, multiply 240 by 0.15, which equals 36. Percent means 'per hundred,' so 15% is 0.15 in decimal form. This is a basic percentage calculation.

Two from the bank, answered.
Real items, with the answer marked and the reason written out — the same format as all 401.
Language Arts
Choose the sentence that is written correctly.
- ANeither the manager nor the employees were ready for the audit.Correct
- BNeither the manager nor the employees was ready for the audit.
- CNeither the manager nor the employees is ready for the audit.
- DNeither the manager or the employees were ready for the audit.
Why: With 'neither/nor,' the verb agrees with the nearer subject, which is 'employees' (plural), so 'were' is correct. The correlative conjunction requires 'nor,' not 'or.' This is a standard subject-verb agreement rule for compound subjects.

GED, by the numbers.
| Questions | Not published by GED Testing ServiceGEDTS gives no question count for any of the four subjects. It describes the formats only: multiple choice plus drag-and-drop, fill-in-the-blank, select-an-area and drop-down items; Mathematical Reasoning in two parts; and Reasoning Through Language Arts in three sections that include one written essay (extended response). |

| Passing score | Scaled score of 145 on a 100–200 scaleOn each of the four subjects, separately. GEDTS: “The GED® test has a passing score of 145 for each test subject. To earn your high school equivalency, you'll need to score 145 or higher on all four subjects.” Scores are not averaged across subjects, and 145 is a scaled score, not a percentage. GEDTS also reports two higher levels on the same scale — GED College Ready (165–174) and College Ready + Credit (175 and above). Retakes: after a first attempt you get two further retests at any time; if you have not passed within 3 attempts, you wait 60 days before each further attempt. |
