Question

4. The number of boys in a school is double that of the girls . What
is the number of boys, if the total number of students in the school
0
is 450?​

Answer 1

Answer:

Let the number of girls be x

&

Let the number of boys be 2x

Therefore,

x + 2x = 450

3x = 450

x = 450/3

x = 150

If the number of girls (x) is equal to 150 then,

The number of boys(2x) = 2 * 150

2x = 300

Hence, the number of boys and the number of girls respectively are 300 and 150.
