so simple yaar. chill. Can't you solve this No problem i will tell you how to solve

No. of students in the school = 1800

No. of students in the school = 1800Percentage of girls = 55%

No. of students in the school = 1800Percentage of girls = 55%Percentage of boys = 45%

No. of students in the school = 1800Percentage of girls = 55%Percentage of boys = 45%No. of boys = (45÷100)×(1800-x)

No. of students in the school = 1800Percentage of girls = 55%Percentage of boys = 45%No. of boys = (45÷100)×(1800-x)1800 - x = \frac{45}{100}1800−x=10045

No. of students in the school = 1800Percentage of girls = 55%Percentage of boys = 45%No. of boys = (45÷100)×(1800-x)1800 - x = \frac{45}{100}1800−x=10045- x = \frac{45}{100 } \times 1800−x=10045×1800

No. of students in the school = 1800Percentage of girls = 55%Percentage of boys = 45%No. of boys = (45÷100)×(1800-x)1800 - x = \frac{45}{100}1800−x=10045- x = \frac{45}{100 } \times 1800−x=10045×180045 × 18 = x

No. of students in the school = 1800Percentage of girls = 55%Percentage of boys = 45%No. of boys = (45÷100)×(1800-x)1800 - x = \frac{45}{100}1800−x=10045- x = \frac{45}{100 } \times 1800−x=10045×180045 × 18 = x× = 810

Answer 2

Answer:

       

No. of students in the school = 1800

Percentage of girls = 55%

Percentage of boys = 45%

No. of boys = (45÷100)×(1800-x)

1800-x=45/100

-x=45/100×1800

45 × 18 = x

× = 810
