How much time will it take to fill the water tank of 80 cm x 60 cm x 50 cm?
A water pump has a capacity to fill water at 10 liters per second. How much time will it take to fill the water tank of 80 cm x 60 cm x 50 cm?
(a) 12 Seconds
(b) 24 Seconds
(c) 36 Seconds
(D) 48 seconds
Answer: (b) 24 Seconds
Solution:-
The depth, width and length of a tank = 80 cm. 50 cm and 60 cm.
Then, the volume of the tank = 80 x 50 x 60
= 240,000 cm^3
As we know that, 1000 cm^3 = 1 lit
Therefore, 240,000 cm^3 = 240,000/1000
= 240 liters
A pump has a capacity to fill water at 10 liters/sec
Then, Time taken by pump to fill the tank = 240/10
= 24 sec.
Hence, the correct answer is option (b) 24 seconds.
