The scale on a topographic map is 1:50,000. If the measured distance between two schools on the map is 8 cm, what is the actual direct distance between them in kilometers?
- 0.4 km
- 4 km
- 40 km
- 400 km
Show answer & explanation
Answer: B. 4 km
At a 1:50,000 scale, 1 cm on the map represents 50,000 cm in reality. Therefore, 8 cm represents 8 x 50,000 = 400,000 cm. Since 100 cm = 1 m and 1,000 m = 1 km, 400,000 cm = 4,000 m = 4 km.

A municipality charges for monthly household water usage using a stepped tariff system: the first 6 kL are free; usage from 6 kL up to 15 kL is charged at R12 per kL; and usage above 15 kL up to 30 kL is charged at R20 per kL. If a household uses 18 kL of water in a month, what is their total bill?
- R168
- R240
- R360
- R144
Show answer & explanation
Answer: A. R168
The first 6 kL are free (R0). The next step of usage is from 6 kL to 15 kL, which is 9 kL charged at R12/kL = R108. The remaining usage above 15 kL is 18 - 15 = 3 kL, charged at R20/kL = R60. The total bill is R108 + R60 = R168.

A retailer increases the price of a winter coat by 20%. During a clearance sale, the retailer marks the new price down by 20%. What is the overall percentage change from the original price of the coat?
- No change
- 4% increase
- 4% decrease
- 2% decrease
Show answer & explanation
Answer: C. 4% decrease
Let the original price be 100. After a 20% increase, the price is 120. A 20% markdown on 120 is 0.20 x 120 = 24. The final price is 120 - 24 = 96. This represents a 4% decrease from the original price of 100.

A motorist embarks on a 350 km trip. She drives at an average speed of 100 km/h for the first 2 hours, then stops for a 30-minute rest break, and completes the remaining distance of the trip in 1.5 hours. What was her average speed for the entire journey, including the stop?
- 100 km/h
- 87.5 km/h
- 92.5 km/h
- 80 km/h
Show answer & explanation
Answer: B. 87.5 km/h
Total distance is 350 km. Total elapsed time is 2 hours (driving) + 0.5 hours (break) + 1.5 hours (driving) = 4 hours. Average speed = Total Distance / Total Time = 350 km / 4 hours = 87.5 km/h.

A cylindrical rainwater storage tank has a diameter of 2 meters and a height of 3 meters. Assuming pi is approximately 3.14, what is the approximate volume of the tank in liters? (1 cubic meter = 1,000 liters).
- 9,420 liters
- 37,680 liters
- 3,140 liters
- 18,840 liters
Show answer & explanation
Answer: A. 9,420 liters
The radius (r) of the cylinder is 1 m (half of the 2 m diameter). Volume = pi x r^2 x h = 3.14 x (1^2) x 3 = 9.42 cubic meters. Converting to liters: 9.42 x 1,000 = 9,420 liters.

A building contractor mixes cement, sand, and stone in the ratio of 1:2:4 by volume to make concrete. If the contractor needs to prepare 35 cubic meters of concrete, how many cubic meters of sand are required?
- 5 cubic meters
- 10 cubic meters
- 20 cubic meters
- 15 cubic meters
Show answer & explanation
Answer: B. 10 cubic meters
The total parts in the ratio are 1 + 2 + 4 = 7 parts. Sand represents 2 parts out of the 7. The required volume of sand is (2/7) of 35 cubic meters = 10 cubic meters.

A small bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. If two marbles are drawn at random one after the other without replacement, what is the probability that both marbles drawn are green?
- 1/25
- 1/45
- 1/15
- 1/50
Show answer & explanation
Answer: B. 1/45
The total number of marbles is 5 + 3 + 2 = 10. The probability of drawing a green marble first is 2/10 = 1/5. Since there is no replacement, there is now 1 green marble left out of 9 total marbles. The probability of drawing a green marble second is 1/9. The combined probability is (2/10) x (1/9) = 2/90 = 1/45.
