Answer: Country A - 10machines

Country A - 1,000machines

Country A - 10,000machine

step-by-step explanation:

Since 10℅ of all machines becomes worthless every year, let's look at each country.

If 100 machines are all the machines in country A, then 10% of all the machines in country A (i.e 100 machines) will be 10% of 100 = 10 machines.

Similarly for country B, it will be equivalent to 10% of 10000, which is equal to 1,000machines.

Same goes for country C i.e 10% of 1000000 = 10,000machines are worthless.
