Question

in a school 2/5 upon 54 of the students are girls and the rest are boys if the number of boys is 2030 find the number of girls

Answer 1

Let the total number of students be x...
now accrdng to question 25/54 into x are girls
therefore 1-25/54 into x will be number of boys that is 29/54 into x..


now it is given that no of boys are 2030
hence
29/54 into x = 2030
hence x=3780
thus total number of students are 3780...

then no of girls=total students-no of boys
                     =3780-2030
                     =1750...
