Solved Questions on Capacity
Fill in the blank:
(850 ÷ 5 × 30) dL = __________ hL
a) 0.051
b) 0.51
c) 5.1
d) 51
Answer: c) 5.1
Explanation: (850 ÷ 5 × 30) dL = [(850 ÷ 5) × 30] dL [Using BODMAS]
= (170 × 30) dL
= 5100 dL
= 5100/1000 hL
= 5.1 hL
2. A dairy farm produced 1200 litres of milk last month. The production for each day was 42.15 litres this month. What is the difference in the amount of milk in millilitres produced if both months are 30 days?
a) 6.45 mL
b) 645 mL
c) 6450 mL
d) 64500 mL
Answer: d) 64500 mL
Explanation: A dairy farm produced litres of milk last month = 1200 L
Farm produced litres of milk this month = 42.15 × 30
= 1264.5 L
Difference in production of milk = (1264.5 − 1200) L
= 64.5 L
Difference in production of milk in mL = 64.5 × 1000
= 64500 mL
3. The tank is filled to 3/8th of its capacity and the total capacity of the tank is 200 hL. What is the amount of water in litres that can be filled to the brim?
a) 750 L
b) 7500 L
c) 1250 L
d) 12500 L
Answer: d) 12500 L
Explanation: Total capacity of the tank = 200 hL
Tank is filled = (3/8) × 200
= 75 hL
Amount of water that can be filled to the brim = 200 − 75
= 125 hL
Amount of water in litres that can be filled to the brim = 125 × 100
= 12500 L
4. Convert the quantity 143.735 decalitres into kilolitres.
a) 1.4374 kilolitres
b) 14.374 kilolitres
c) 143.74 kilolitres
d) 1437.4 kilolitres
Answer: b) 14.374 kilolitres
Explanation: 143.735 decalitres = 143.735 ÷ 100 kilolitres
= 1.43735 kilolitres
= 1.4374 kilolitres
5. 700 gallons are filled in the fuel tank of an aeroplane. What is the amount of fuel left in pints if the fuel used is 1600 quarts?
a) 1200
b) 1600
c) 2400
d) 2800
Answer: c) 2400
Explanation: Capacity of fuel tank of an aeroplane = 700 gallons
Fuel used = 1600 quarts
= 1600 ÷ 4
= 400 gallons
Amount of fuel left in the tank = 700 - 400
= 300 gallons
Amount in pints of fuel left in the tank = 300 × 8
= 2400 pints
