Vedclass · Answer

(A) Total number of students $= 504$.Ratio of boys to girls $= 13: 11$.Sum of ratio terms $= 13 + 11 = 24$.Number of boys $= \frac{13}{24} 	imes 504 = 13 	imes 21 = 273$.Number of girls $= \frac{11}{24} 	imes 504 = 11 	imes 21 = 231$.If $12$ more girls are admitted,the new number of girls $= 231 + 12 = 243$.The number of boys remains $273$.New ratio of boys to girls $= 273: 243$.Dividing both by $3$,we get $\frac{273}{3} : \frac{243}{3} = 91: 81$.
