Question

In a school,58% of the total numbers of the students are boys. If the number of girlsis 840, how many students are there in the class?

Answer 1

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

Answer 2

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
