numerical reasoning question i'm stuck on, any help please?

#1

If I had funds available in all currencies, what would be the most favourable currency with which to pay an order of aircraft parts worth £5,652,775?

Exchange rates for sterling (£):
Euro - 1.50
Japanese Yen - 191.47
US dollars - 1.65

possible answers are as follows:

a) Sterling
b) Euro
c) Japanese Yen
d) US dollar
e) Cannot say

Cannot say

Imo the answer is e) cannot say. There is no way you can decide which currency is the best to pay for the order, because there is not enough info. So you have the exchange rates, but they don’t really help unless you know how they have changed. I just can’t see any other solution.
