NTN Fireteam Math — Practice Revision Set 1
I’ll use practice-style questions, not claim these are leaked or guaranteed actual exam
questions.
1. What is 25% of 240?
A. 40
B. 50
C. 60
D. 80
CORRECT ANSWER: C. 60
Working:
25% = 25/100 = 0.25
0.25 × 240 = 60
Exam Point:
25% = ¼ of a number.
2. A firefighter travels 180 km in 3 hours. What is the average speed?
A. 45 km/h
B. 50 km/h
C. 60 km/h
D. 90 km/h
CORRECT ANSWER: C. 60 km/h
Working:
Speed = Distance ÷ Time
= 180 ÷ 3
= 60 km/h
,3. A tank contains 800 litres of water. If 35% is used, how many litres remain?
A. 280 L
B. 420 L
C. 520 L
D. 560 L
CORRECT ANSWER: C. 520 L
Working:
35% of 800 = 280 L
800 − 280 = 520 L
4. Calculate:
3/4 + 2/3
A. 5/7
B. 17/12
C. 13/12
D. 7/12
CORRECT ANSWER: B. 17/12
Working:
LCM of 4 and 3 = 12
3/4 = 9/12
2/3 = 8/12
9/12 + 8/12 = 17/12 = 1 5/12
5. A fire hose delivers 120 litres of water per minute. How much water will it deliver in 8
minutes?
A. 720 L
B. 840 L
C. 960 L

firefighters take?
A. 3 hours
B. 6 hours
C. 12 hours
D. 24 hours
CORRECT ANSWER: B. 6 hours
Working:

12 ÷ 2 = 6 hours
7. A ladder is 10 m long and reaches a vertical height of 8 m. How far is its base from the wall?
A. 4 m
B. 5 m
C. 6 m
D. 8 m
CORRECT ANSWER: C. 6 m
Working: Using Pythagorean theorem:
10² = 8² + x²
100 = 64 + x²
x² = 36
x=6m
8. Convert 2.5 hours into minutes.
A. 120 minutes
B. 135 minutes
