Exchange rate in Kazakhstan

About 2 hours ago I received an important call, from my friend, about exchange rate in Kazakhstan. So 10 hours ago current rate of dollar was: 

120 tenge - 1 dollar. but now it's 160 tenge per dollar

For compare I put some more information:

10 hours ago

1 USD - 120 Kzt, where USD - United State dollar, Kzt - kazakhstan tenge

1 Euro - 160 kzt

1 GBP - 179 kzt, where GBP is great Britain pound(who didn't know yet =-./  )

Now:

1 USD - 160 Kzt

1 Euro - 196 Kzt

1 GBP - 170 Kzt

We can see huge difference in numbers. 

I hope that I counted correctly:

Change in percentage:

USD grow up by 25%

Euro 18% up

GBP 5% down

Please correct me, if I'm not correct.

Btw(by the way) I'm predicting that this rate of currency exchange will hold for 2 weeks...

Thanks for reading my blog!
