In the​ 2009-2010 school year in country​ A, there were 106 comma 000 foreign students from country B. This number is 21​% more than the number of students from country C. How many foreign students were from country​ C?

Answer 1

Answer:

There were 87903 students from country C.

Step-by-step explanation:

Let suppose n be the number of students from country C

Then

$\mathrm{121\%\:\times \:n=106000}$

$\frac{121}{100}n=106000$

$121n=10600000$

$n=\frac{10600000}{121}$

$n=87603$

Therefore, there were 87903 students from country C.

Verification:

21% of 87603 = 18397

87603 + 18397 = 106000
