Milly bought a pair of gloves and a skirt. The gloves cost £3. She sold the gloves and skirt for a total of £42. She made 100% profit on the cost of the gloves and 40% profit on the total cost. Work out her percentage profit on the cost of the skirt to 1d.p

I have no idea how to find out how much they were both bought for.

% profit means the percentage of money she got back as a percentage of the cost she bought them for, so it should be fairly simple to work out how much the gloves were sold for. Take this away from 42, and that's how much the skirt was sold for.
It tells you that she made 40% profit on the total cost. That means that £42 is 140% of the total original cost of the gloves and skirt. If 42 = 140%, you can find 100%. The question tells you how much the gloves cost, so you can use that to work out how much the skirt cost. Once you've got the cost of the skirt and the amount of money she sold it for you can work out the percentage profit on the skirt.
