A) 30 birds
B) 60 birds
C) 72 birds
D) 90 birds
Correct Answer: A
Solution :
Let the total number of shots be x. Then, shots fired by \[A=\frac{5}{8}x;\] Shots fired by \[B=\frac{3}{8}x.\] Killing shots by \[A=\frac{1}{3}\,\,\text{of}\,\,\frac{5}{8}x=\frac{5x}{24};\] Shots missed by \[B=\frac{1}{2}\,\,\text{of}\,\,\frac{3}{8}x=\frac{3x}{16}\] \[\therefore \] \[\frac{3x}{16}=27\] or \[x=\left( \frac{27\times 16}{3} \right)=144\] Birds killed by \[A=\frac{5x}{24}=\left( \frac{5}{24}\times 144 \right)=30\]You need to login to perform this action.
