Molly bought a pair of gloves and a skirt. The gloves cost £3. She sold the gloves and the skirt for a total of £42. She made 100% profit on the cost of the gloves. 40% profit on the total cost. Work out the percentage profit on the cost of the skirt

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
