    really hard percentage, ratio and indices question

    hi this is my question:

    Ali has 12% of 350kg of apples, James had 13% of left over. Helen and Jack divided the remaining in ratio of 2:3.

    how many kg of apples each person had?
    write in form of indices
    first of all i found out ali has 42kg of apples and james has 40.3kg of apples.

    i don't know what to do on the rest, can anyone help please?

    Ali has 12 % of 350kg\of apples=42kg
    James had 13% of left over=13% of 308 = 40.04 kg or 40 kg 40 g
    Helen and Jack divided the remaining (267.96 kg) in ratio of 2:3
    therefore Helen got  = 267.96\times  \frac{2}{2+3} = 107.184 \ kg =107 \ kg 184 \ gram
    and Jack got  = 267.96\times  \frac{3}{2+3} = 160.776 \ kg =160 \ kg 776 \ gram

    there is any mistake in your calculations

    james had 13% of left over(350-40=308 apples)=13% of 308 = \frac{13}{100} \times 308 = 40.04 kg or 40 kg 40 g
