Question

II. 9. In a school, 58% of the total number of students is boys. If the number of girls is 840, how many students are there in the class? d 2100​

Answer 1

2,000 students

Explanation:

If 58% of the students are boys then 42% of the students are girls

43% = 42/100 = 0.42

Actual number of girls = 840

If x is the total number of students then 0.42x = number of girls

0.42x = 840

x = 840/0/42

= 2,000 students
