Introduction
This Quantitative Proficiency Examination is designed to rigorously assess a candidate's command over
essential mathematical principles, analytical reasoning, and applied problem-solving skills. The test
comprises 200 multiple-choice questions, structured to evaluate foundational theory, practical
application, regulatory understanding, and ethical decision-making within quantitative contexts.
Candidates will engage with a diverse array of scenarios, from basic arithmetic to complex data
interpretation, ensuring a comprehensive evaluation of their readiness for professional environments. The
emphasis is on real-world application, requiring test-takers to demonstrate not just computational
accuracy but also strategic thinking and the ability to make informed, data-driven decisions. Each
question is accompanied by a detailed rationale to reinforce learning and understanding.
SECTION ONE: QUESTIONS 1 – 100
Question 1
A company's revenue increased from $500,000 to $625,000 over the course of a year. What is the
percentage increase in revenue?
A. 20%
B. 25%
,C. 30%
D. 35%
🟢 B. 25%
🔴 Explanation: The percentage increase is calculated as [(New Value - Old Value) / Old Value] × 100.
Here, [(625,000 - 500,000) / 500,000] × 100 = (125,,000) × 100 = 0.25 × 100 = 25%. Option B
is correct.
Question 2

A. 3
B. 5
C. 7
D. 9
🟢 B. 5
🔴 Explanation: Subtract 7 from both sides: 3x = 15. Then divide by 3: x = 5. Option B is correct.

🟢 B. 22
🔴 Explanation: The median is the middle value in an ordered set. With seven numbers, the fourth
value is the median. The ordered set is 12, 15, 19, 22, 28, 31, 35; the fourth value is 22. Option B is
correct.

A. 120 miles
B. 125 miles
C. 150 miles
D. 180 miles
🟢 C. 150 miles
🔴 Explanation: Distance = Speed × Time. 60 miles/hour × 2.5 hours = 150 miles. Option C is correct.
Question 7
Simplify the expression: 4(2x + 3) - 2(3x - 1)
A. 2x + 10
B. 2x + 14
, C. 8x + 12
D. 8x - 6
🟢 B. 2x + 14
🔴 Explanation: Distribute: 8x + 12 - 6x + 2 = (8x - 6x) + (12 + 2) = 2x + 14. Option B is correct.
Question 8
What is 15% of 200?
A. 25
B. 30
C. 35
D. 40
🟢 B. 30
🔴 Explanation: 15% of 200 = 0.15 × 200 = 30. Option B is correct.
Question 9
A dataset has a mean of 50 and a standard deviation of 5. What is the z-score for a value of 60?
A. 1.0
B. 1.5
C. 2.0
D. 2.5
🟢 C. 2.0
🔴 Explanation: The z-score is calculated as (Value - Mean) / Standard Deviation. Here, (60 - 50) / 5 =
= 2.0. Option C is correct.
Question 10
Solve for y: 2y - 5 = 3y + 10
A. -15
B. -5
C. 5
D. 15
