A fires 5 shots to B's 3 but A kills only once in 3 shots while B kills once in 2 shots. When B has missed 27 times, A has killed:

30 birds
60 birds
72 birds
90 birds

Correct Answer: 30 birds

Explanation:

Let the total number of shots be x . Then,

Shots fired by A =	5	x
	8

Shots fired by B =	3	x
	8

Killing shots by A =	1	of	5	x	=	5	x
	3		8			24

Shots missed by B =	1	of	3	x	=	3	x
	2		8			16

∴	3x	= 27 or x =	❨	27 x 16	❩	= 144.
	16			3

Birds killed by A =	5x	=	❨	5	x 144	❩	= 30.
	24			24
