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 \[=\frac{176}{110+22}=\frac{176}{132}=\frac{4}{3}=4:3\]You need to login to perform this action.
