    It does not matter which way round you have your axes.

    For the contribution line you can use any total contribution you want because all you want is the angle of it. Better to use 20p+40s = 400,000 – then you will get a decent line.

    You’ve told it doesn’t matter whether we put snooker cues at x or at y axis..

    In the solution they have put snooker cues on x-axis, whereas i have put snooker cues on y-axis,
    my optimal solution lies at point b, whereas theirs at point d,
    the reason is because x<15000 (snooker cues) and y<12000 (pool cues) whereas they have taken the opposite?

    and for the iso contribution line, 20x+40Y = 80000, is this okay? but then it doesnt give the optimal solution at point d?

    Thanks in advance..

    But the question says that pool cues are limited to 15,000 and snooker cues are limited to 12,000, so the answer is correct.

    I think you must have misread it and that will be why you get a different optimal solution.
