【明報專訊】Pat is making a tiramisu. She has got all the ingredients from the grocery but she forgot her measuring cup! She can only make do with two unmarked containers of 400ml and 700ml. How can she measure out exactly 500ml whipped cream for her tiramisu?

Tips:

You may start by filling the 400ml cup, then transfer the content to the 700ml container... It sounds complicated, but actually only involves simple mathematical calculation!
