If the number of patients increases by 10% every year in Europe, then what is the difference between the number of patients in Europe after two years and the number of kidney patients in South America in 2023?
The difference is 8 lakh, so that is the answer.
There are 80 crore patients, and Europe has 10 percent, which is 8 crore.
Growing 8 crore by 10 percent for two years gives about 9.68 crore.
Kidney patients in the world are 24 crore, of which South America has 40 percent.
That is 9.6 crore kidney patients in South America.
The difference between 9.68 crore and 9.6 crore is 8 lakh.
