Level 2

Container A and Container B are fully filled with water. If all the water in Container A is poured into Tank C, it is 30 litres short of filling it to the brim. If all the water in Container B is poured into the same tank, it is 56 litres short of filling it to the brim. If the water from both containers is poured into the same tank, it will completely fill it. If both Tank C and Container B are completely filled, how much more water can Tank C fill than Container B?

The figure shows a tank made up of 3 sections. Cuboid A with a square base of side 4 cm and height 30 cm. Cube B with a side of 12 cm. Cuboid C that is 60 cm by 20 cm by 40 cm. Water from a tap above flows down at a rate of 1.2 litres per minute while water is drained out from the bottom at a rate of 1 litre per minute. How long did it take to fill up the tank to a height of 66 cm from the base? Give the answer in minutes correct to nearest whole number.

Shemy placed three empty tanks side by side. The smallest tank has a crack at its side and the base area of each tank is 16 cm^{2}. After she turned on the tap for 64 minutes, the height of the water in the smallest tank became 6 cm although 0.5 mℓ of water is leaking out of the crack per minute. Find the rate of flow of water from the tap. Give the answer in mℓ/min.
