Answer :
Girls = 484
Given :
Girls = 45 %
Boys = 440
According to the question :
Let the total students be ' x '
Girls = 45 % of x
=> 45 / 100 × x
=> 45 / 100x
=> 9 / 20x
Boys = 440
To find the no. of. girls :
❍ Total = Girls + Boys
=> x = 9 / 20x + 440
=> 440 = 9 / 20x - x [ LCM = 100 ]
=> 440 = ( 9 × 5 / 20x × 100 ) - ( x / 100 × 1 )
=> 440 = 45x - x / 100
=> 440 = 44x / 100
=> 440 = 11 / 10
=> 11 / 10 × 440
=> 484
So, It's Done !!
