So how much is it? Initially I studied the currency unit "Qatar riyal".

Qatar Rial - Wikipedia, the free encyclopedia

In fact, since 1980 1 US dollar = 3.64 Rial, fixed at 1 Rial = 0.274725 US dollars. This rate became official in July 2001.

In other words, 10 million rials mean that,

10000000 Riyal × 0.274725 dollar = 2,747,250 dollars

That is, about 300 million yen in Japanese yen! There is money where there is 300 million yen for one mobile phone number ... ....
