During a certain period, the exchange rate were follows:

1 sterling pound = Kshs. 102.0
1 sterling pound = Kshs. U.S dollar
1 U.S dollar = Kshs. 60.6

A school management intended to import textbooks worth Kshs 500,00 from U.K. It changed the money to sterling pounds. Later the management found out that books were cheaper in U.S.A. Hence it changed the sterling pounds to dollars. Unfortunately, a financial crisis arose and the money had to be reconverted to Kenya shillings.
Calculate the total amount of money the management ended up with.
