Inspired by his recent trip to the Great Pyramids, Citibank trader Ruminder Dhillon wonders if he can make an intermarket arbitrage profit using Libyan dinars and Saudi riyals. He has $$1,000,000$ to work with, so he gathers the following quotes:

Citibank quotes U$.$S$.$ dollar per Libyan dinar: $$0\mathrm{.}7200$ per LYD

National Bank of Kuwait quotes Saudi riyal per Libyan dinar: SAR $2\mathrm{.}7200$ per LYD

Barclay quotes U$.$S$.$ dollar per Saudi riyal: $$0\mathrm{.}2700$ per SAR
