Correct Answer - Option 3 : 1600
Given:
Total number of girls in school is 720
55% of the students are boys.
Calculation:
Out of 100%, 55% are boys,
Number of Girls,
⇒ 100 – 55 = 45%
According to the question,
⇒ 45% = 720
⇒ 1% = 720/45
⇒ 1% = 16
Total number of students,
⇒ 100 × 16
⇒ 1,600
∴ Total number of students are 1,600.
