Final answer:
Mitsubishi UFJ Financial Group forecasts that the Australian dollar will weaken by 5% over the next year. The future exchange rate is estimated to be ¥64.334/A$ based on this forecast.
Step-by-step explanation:
Mitsubishi UFJ Financial Group forecasts that the Australian dollar will weaken by 5% over the next year. To calculate the future exchange rate, we need to account for this depreciation.
Currently, the exchange rate is ¥67.72/A$. If the Australian dollar weakens by 5%, we need to calculate 5% of the current rate and subtract it from the current rate.
5% of ¥67.72 is ¥3.386. Subtracting ¥3.386 from ¥67.72 gives us a forecasted exchange rate of ¥64.334/A$.
