 Ayush sold one million Japanese Yen to buy GBP. But then he realized that he did not need GBP, so he used these GBP to buy Australian dollars. How many Australian dollars did he buy? Round your answer to the nearest Australian dollar. Show every step of the calculation.
 A week later, Manav returned to the airport and saw he same sign. He had 500 GBP left over and he used these to buy Canadian dollars. How many Canadian dollars did he buy? Round your answer down.
