Hello thanks for looking, hope I’m posting in the right forum and have worded this correctly to get the result I’m look for, so here goes...

To make a 60ml concentrate the calculation would be...

If 10ml of 60ml was already 100% Apple and to make the mix complete the final 60ml mix including the 10ml needed to be 70% Apple and 30% Blackcurrant, how would you work out what % of Apple and Blackcurrant are needed to mix up the 50ml.

Thanks in advance
