do I do this?

1. Given the following two sets of quotations by two currency dealers: a. State, just by observation, without any calculations or explaining the transactions (that's coming in part b), whether these two sets of quotations are out of equilibrium to a degree that would lead to an arbitrage opportunity in the absence of any transaction costs beyond the bid/ask spread. b. Now, prove your point by narrating the trading activities that you need to perform and by calculating any arbitrage profit if you start with a nominal sum of $68 million. 2. Given the following three currency quotes given by a Swiss bank and a London bank: $1.0840/SF0.8864/SF0.8475/$ Please answer parts (a) and (b) in the order they are given. a. Show whether there is an arbitrage opportunity implied in these three quotes (do not inverse any of the inputs (given quotes). If need be you inverse an output (an answer). b. Starting with a nominal $42 million, show by explaining the transactions and by calculations how much arbitrage profit (if any) you can make by trading the currencies at the given rates
