Complete question:
Container x contained 1200g of sand. Container y contained 7.2kg of sand. After as equal amount of sand was removed from each container, Container Ynow has 7 times as much as sand as container x. How much sand was removed from each container?
Answer: the mass of sand removed from both containers is 0.2kg
Step-by-step explanation:
Given that:
Mass of sand in container X = 1200g = 1.2kg
Mass of and in container Y = 7.2kg
Equal amount of sand was removed from both.
Let the mass of sand removed from both containers = z
That is;
Container X = 1.2 - z
Container Y = 7.2 -z
Now container Y has become 7times the content in container X
Container Y = 7 * (container X)
7.2 -z = 7(1.2 - z)
7.2 - z = 8.4 -7z
-z + 7z = 8.4 - 7.2
6z = 1.2
z = 0.2
Therefore, the mass of sand removed from both containers is 0.2kg
