Answer 1

let the number of total students be x
A.TQ
girls=35/100×x
35x/100=x-910
35x/100-x=910
35x-100x÷100=910
-65x/100=910
-65x=910×100
x=91000÷-65
x=-1400

Answer 2

Given :

35% are girls

Number of boys = 910

To find :

Number of girls

Total Number of students

Solution :

Finding percentage of boys :

100% - 35% = 65% (boys)

Finding Number of girls:

given boys are 910

if 65% = 910 boys

then 35% = ? girls

35 x 910 ÷ 65 = 31850 ÷ 65 = 490

Hence the number of girls = 490.

Finding number of students :

Total enrollment = boys + girls

Total enrollment = 490 + 910 = 1400.
