A) 48
B) 84
C) 92
D) 108
Correct Answer: B
Solution :
Suppose the number of addition of boys and girls is x. So, by question \[\frac{20+x}{32+x}=\frac{3}{4}\] \[\Rightarrow \] \[(4x-3x)=(32\times 3-20\times 4)\] \[\Rightarrow \] \[x=96-80=16\] So, the total numbers at present \[=36+48=84\]You need to login to perform this action.
