Step-by-step explanation:

13x + 11 + = 504

x = 504/24 = 21

लड़के = 21 × 13 = 273

लड़किया = 21 × 11 = 231

12 लड़कियां को भर्ती करने पर उनकी संख्या = 231 + 12

= 243

अनुपात = 273/243 = 91/81 = 91:81, Answer

Answer:

91:81

Step-by-step explanation:

The total no of children = 504 students.

The ratio between girls and boys = 13:11

No. of girls = 11/ 24 × 504 =231 girls

No of boys = 504 -231 =273 boys

No of newly added girls= 12.

Total no of girls now =( 231+12) girls = 243 girls.

The new ratio = 273 / 243 = 91/81 = 91:81.

hope it helps you..
