George and Martha’s council has 40 seats shared between Labour, Conservatives and Democrats. Before a recent election, Labour had an overall majority, with Conservatives second. After it, the order was Conservatives first, Labour second, Democrats third, both Conservatives and Democrats having improved their numbers of seats. To achieve a majority, the Conservatives formed a coalition with the Democrats. Each party had a whole two-figure number percentage change in its number of seats; the Democrats’ percentage increase was an odd number.
How many seats did each party win?
