A.
30 birds
B.
60 birds
C.

90 birds
View Answer
Correct choice: A
Explanation:
Let the no of shots be x. Then, Shots fired by A =(5/8)x Shots fired by B = (3/8)x Killing shots by A = 1/3 of (5/8)x = (5/24)x Shots missed by B = 1/2 of (3/8)x = (3/16)x (3/16)x = 27 ⇒⇒ x =144 Birds killed by A = (5/24)x = (5/24)*144 = 30
