Question

There are 1200 students in a school if the number of girls are double than the boys find the number of boys and girls

​

Answer 1

x = the number of boys

2x = the number of daughters

there are 1200 students

we write the following equation

x+2x=1200

3x=1200

we solve

3x=1200

x= 400

there are 400 boys, 400*2=800 girls

Explanation:

Answer 2

boys = 400

girls = 800

Explanation:

let the number of boys be = X

the number of girls be = 2X ( 2 because as mentioned girls are double the boys)

total number of student in school= 1200

X + 2X = 1200 (According to the question boys + girls = total of students)

3X = 1200

X = 1200 / 3

X = 400

2X= 400 * 2

2X = 800
