Several litres of acid were drawn off from a 54 litre vessel full of acid and equal amount of water was added. Again the same volume of the mixture was drawn off and replaced by water. As a result now, the vessel contained 24 litres of pure acid. How much of the acid (in litres) was drawn off initially?

A man ordered 4 pairs of black shoes and some pair of brown shoes. The price of black shoes is twice to that of brown shoes. While preparing the bill the clerk interchanged the number of black and brown pairs of shoes by mistake, which increase the bill by 40%. What is the total number of black and brown shoes?
