3 identical basins, A, B, C were filled with water. Basin A had a mass of 3.1kg when it was half full. Basin B had a mass of 2.2kg when it was 1/5 full. What fraction of basin C was filled with water when it hsd a mass of 2.8kg
I didn't understand many key concept.
Like ,
1.if it's half full and weighs 3.1 kg doesn't it means when it's full totally it should weighs 3.1 * 2 = 6.2
2.Identical basins, does this mean A, B,C = A then why they bother to write that down?
3.If these basins are not symmetric in every direction then why did it says one of them was half filled.
