    In a school having roll strength 286, the ratio of boys and girls is 8 : 5. If 22 more girls get admitted into the school, the ratio of boys and girls becomes

    A) 12 : 7

    B) 10 : 7  

    C)  8 : 7    

    D)  4 : 3

    Correct Answer: D

    Solution :

    Initially number of boys \[=\frac{8}{8+5}\times 286=\frac{8}{13}\times 286=176\] \[\therefore \] Number of girls\[=\frac{5}{13}\times 286=110\] 22 more girls get admitted \[\therefore \] Required ratio \[=\frac{176}{110+22}=\frac{176}{132}=\frac{4}{3}=4:3\]
