    Worst school? Ok then big **** search charter house and then tell me I got to the worst in the country ****** hahaha. Funny how you are self consciously trying to reassure yourself that you got it right by correcting other people that probably got it right, thick piece of ****. Really reflects your intellectual aptitude doesn't it?
    I don't care what you are trying to say or if you're angry who the **** do you think you are using the word ****** like that. That's disgusting.

    It didn't ask for 3 significant figures, because it was an exact answer.

    Can someone tell me if I got the ratio question right

    The question was A, B and C share 6000 (insert currency here) into the ratio 2 : 3 : 7
    C then gives 3/5 of his share to D.
    What percentage of the original total currency does D now have.

    People are saying it is 38% but I got 35% here is how:

    2 + 3 + 7 = 12
    Therefore 1 share = 6000/12 = 500

    C got 7 shares so he got 3500 (currency)

    C then gave 3/5 of his share to D so I did 3500 x 3/5 = 2100

    Then I did 2100/6000 = 0.35 which is 35%.

    Where did I go wrong?? I'm a bit concerned. :/

    it was 2100 + 1000 = 3100

    then 3100 / 6000 = 0.516

    X100 =52%

    Why did you add 1000 currency? Did it say somewhere in the question that he already had 1000?

    Yeah, it was 2100+1000=3100.
    You will probably still get two or three out of five.

    I think you need to add his original share onto 2100 rupees. He originally had 1000 rupees (t00x2). That's what I did anyway and I got 52

    He had 2 of the 12 parts in the ratio.

    Ohh I wish I read the question properly sometimes and not just dive into it :/
    I thought Bhavin was some extra person :[
    I don't think this affects my A* seeing as, overall, I lost about 7-8 marks max.
