    Rana sells 192 cakes in the ratio
    Small : medium : large = 7 : 6 : 11
    The profit for one medium cake is twice the profit for one small cake. The profit for one large cake is three times the profit for one small cake. Her total profit is £532.48 so Work out the profit for one small cake.
    Could someone please explain how to work this out? I'm so confused! Thanks

    What have you tried? I think I'd start by working out how many cakes of each type Rana sold.

    Then work out the ratio of the profit of each cake (small:medium:large)
    Add them together, and do the total profit divided by that.

    Do you know how to work out how many of each cake she sold? That is where I would start also.

    Call the profit from the small cake p and form an equation.

    Good luck!

    Ok i am not an expert so it might be wrong but i think it goes like this...
    add 7+6+11 to get 24 as they make up all the cakes. Divide 192 by 24 to get one share which is 8. Times 8 by 7 which is 56 so now you know how much small cakes were sold. As the profit for a medium cake is double the profit for a small cake you can put it in the ratio 1:2 for small:medium cakes. It says the large cake is triple so i believe the ratio is 1:2:3. You add all these up which is 6. Divide 532.48 by 6 to get 88.7..which i think is the total profit. Divide 88.7...by 56 to get the profit of one small cake which is £1.58.
