Currency Conversion Question

Hi all,

I thought this was a basic question, but can not get the right answer.

Ive ended up going around in circles to the point where my logic is all fuzzy so hopefully someone here can help.

So im given this chart:

And asked:

**If you had 120 dollars and 322 euro, how many Yen could you buy?**

I tried this:

Using the 'Ringit' currency ive assumed:

3.25 dollars = 0.03Yen

5.08 euro = 0.03Yen

Purchased Yen for Dollars = (120/3.25) x 0.03 = 1.108

Purchased Yen for Euros = (322/5.08) x 0.03 = 1.902

Total Yen purchasable = 1.108 + 1.902 = 3.01

However the correct answer is 67, 574 - miles from my attempt.

Where am i going wrong?

Thanks
