How many boys are there altogether? I have a answer this question is just for check your mind Ok​

Answer 1

Given

→ Indian boys = 45%

→ Russian boys = 20%

→ American boys = 13%

→ Chinese boys = 44

Solution :-

→ Indian + American + Russian + Chinese= 100 %

But we don't know the percentage of Chinese , so let it x

→ 45 + 13 + 20 + x = 100

→ 78 + x = 100

→ x = 22 %

So Chinese students are 22 percentage .

It implies that 22 percent of total students are 44 in number.

→ (44/ Total students)× 100 = 22%

→ 4400/22 = Total number of students

→ 200 = Total students .

So there are 200 students in the school .
