- A. 0.25 L
- B. 2.5 L
- C. 25 L
- D. 250 L
Answer: B. 2.5 L
1 L = 1000 mL, so 2500 mL = 2500 ÷ 1000 = 2.5 L.
1 L = 1000 mL, so 2500 mL = 2500 ÷ 1000 = 2.5 L.
Rajesh bought 3 kg of sugar and 500 g of salt. What is the total weight in grams?

Which of the following measurements is the smallest?
- A. 1 kilometer
- B. 100 meters
- C. 1000 centimeters
- D. 50,000 millimeters
Answer: C. 1000 centimeters
1000 cm = 10 m, which is the smallest. 1 km = 1000 m, 100 m = 100 m, and 50,000 mm = 50 m.
1000 cm = 10 m, which is the smallest. 1 km = 1000 m, 100 m = 100 m, and 50,000 mm = 50 m.
A farmer has a field of 0.5 hectares. If 1 hectare = 10,000 square meters, how many square meters is the field?
- A. 500 m²
- B. 5,000 m²
- C. 50,000 m²
- D. 5 m²
Answer: B. 5,000 m²
0.5 hectares = 0.5 × 10,000 = 5,000 square meters.
0.5 hectares = 0.5 × 10,000 = 5,000 square meters.
Three water tanks have capacities: Tank A = 1500 L, Tank B = 1.5 kL, Tank C = 15,00,000 mL. Which tank has the largest capacity?
- A. Tank A
- B. Tank B
- C. Tank C
- D. All are equal
Answer: D. All are equal
Tank A = 1500 L, Tank B = 1.5 kL = 1500 L, Tank C = 15,00,000 mL = 1500 L. All have equal capacity.
Tank A = 1500 L, Tank B = 1.5 kL = 1500 L, Tank C = 15,00,000 mL = 1500 L. All have equal capacity.
A factory produces 250 kg of product daily. If the factory operates for 365 days and stores the product at 2 cubic meters per ton, what is the minimum storage space needed in cubic meters?
- A. 18.25 m³
- B. 182.5 m³
- C. 91.25 m³
- D. 1825 m³
Answer: A. 18.25 m³
Total production = 250 × 365 = 91,250 kg = 91.25 tons. Storage needed = 91.25 × 2 = 182.5 m³. Wait, let me verify: 91.25 tons × 2 m³/ton = 182.5 m³, but this doesn't match option A.
