Level 2 PSLE

Carlo filled a container with water using two taps. He turned on Tap A first and after 4 minutes, he also turned on Tap B. Both taps were turned off at the same time when the container was completely filled without overflowing. The graph shows the amount of water in the container over 16 minutes.

The figure is not drawn to scale. Mary poured some water into Tank A and Tank B until the water levels in both tanks were the same. She found out that the total amount of water in both tanks was 32 000 mℓ. She then poured another 1200 mℓ of water into Tank A to fill it to the brim. Find the height of Tank A in the end.

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 is not drawn to scale. It shows a tank made from two connected cubical containers, Cube A and Cube B. The tank is filled with some water. Cube A is^{3}_{4} filled with 6000 mℓ of water while Cube B is completely filled with water. The height of the water level in Cube A is 4 cm higher than that in Cube B. Water is then drained from the tank and the height of the new water level is 5 cm. What is the volume of the water drained in mℓ?
