Answer:
There are 2000 students.
Step-by-step explanation:
Let s be the number of students.
Then the number of boys is 58% of s.
So the number of girls is 100% - 58% = 42% of s
=> 42% of s = 840
=> 0.42 × s = 840
=> s = 840 / 0.42
=> s = 2000

let,
let, the number of students are = 100 x now, 58 x are boys. so, The number of girls is (100 x - 58 x) = 42 x BTP, 42 x / 100 = 840 or, x = 2000 therefore,,,the number of students are = 2000 (ans)

Answer: 2000
Step-by-step explanation:
Total = 100%
Boys = 58%
Hence, girls = 42%
Given, number of girls = 840
42% of total students = 840
42/100 * Total = 840
Total = 840*100/42 = 2000
