DAA DAA Mathematical Reasoning and Arithmetic 2 — Questions and Answers
Question 1: A patrol covers 12 km in 3 hours. What is their average speed in km/h?
- 3 km/h
- 4 km/h (Correct answer)
- 5 km/h
- 6 km/h
Correct answer: 4 km/h
Speed = distance ÷ time = 12 ÷ 3 = 4 km/h.
Question 2: A base has 360 personnel. One-third are on leave. How many remain on base?
- 120
- 180
- 240 (Correct answer)
- 270
Correct answer: 240
One-third of 360 = 120 are on leave, so 360 − 120 = 240 remain.
Question 3: Equipment costs $4,500 and is discounted by 20%. What is the final price?
- $3,200
- $3,400
- $3,600 (Correct answer)
- $3,800
Correct answer: $3,600
20% of $4,500 = $900; $4,500 − $900 = $3,600.
Question 4: A rectangular barracks floor is 15 m long and 8 m wide. What is its area?
- 100 m²
- 110 m²
- 120 m² (Correct answer)
- 130 m²
Correct answer: 120 m²
Area = length × width = 15 × 8 = 120 m².
Question 5: A soldier earns $3,200 per month. After a 15% tax deduction, what is their take-home pay?
- $2,560
- $2,680
- $2,720 (Correct answer)
- $2,840
Correct answer: $2,720
15% of $3,200 = $480; $3,200 − $480 = $2,720.
Question 6: If 5 vehicles can transport 60 soldiers, how many soldiers can 8 vehicles transport?
- 80
- 88
- 96 (Correct answer)
- 100
Correct answer: 96
Each vehicle carries 60 ÷ 5 = 12 soldiers; 8 × 12 = 96 soldiers.
