the number of boys in a school is 334 more than the more than the number of girls if the total strength of the school is 572 find the number of girls in the school

Answer 1

HEY BUDDY..!!

HERE'S THE ANSWER..

_______________________

♠️ Firstly let the number of boys be ( x ) and the number of girls be ( y )

⏺️total strength of school is 572 , i.e

✔️ x + y = 572 _________( 1 )

⏺️ number of boys is 334 more than girls , i.e

✔️ y + 334 = x

=> x - y = 334 __________( 2 )

▶️ Now adding eqn ( 1 ) and ( 2 )

=> x + y = 572

=> x - y = 334
+
___________
=> 2 x = 906
___________

=> x = 906 / 2

=> [ x = 453 ] ✔️✔️

⏺️ Now putting value of x in eqn 1

=> x + y = 574

=> y = 572 - x

=> y = 572 - 453

=> [ y = 119 ] ✔️✔️

♠️ So number of girls are 119 and boys are 453.

Answer 2

Let number of girls in school is X .

Given that : number of boys is 334 more than number of girls.

Number of boys = ( x + 334) .

Total number of students = 334

Number of boys + number of girls = 572

x + x + 334 = 572

2x = 238

x = 119.

Number of girls = x = 119.

And, number of boys = x + 334 = 119 + 334 = 453.
