  1. Use Venn diagrams and this becomes quite easy.

    Start with the intersection of the three circles and place 3 in that regions.
    Now working from the inside out, enter the data
    Make sure you don't count items more than once.
    e.g. for the 10 taking Math and History, remember you already have 3 of those accounted for. So in the region showing ONLY Math and History, place 10-3 or 7
    repeat for the remaining two doubles.
    Now look at the entire circles,
    e.g. the Math circle. Notice that there are already entries in that circle, so make sure you enter only the remaining count from the original 14 in the region showing ONLY Math.

    Add up all the entries and compare that sum with 50
    If the total is less than 50, it would show those students not taking any of the 3 subjects

    Once you have entered all the data, all your questions can be easily determined.
