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:  Choose the correct choice from the following answers.
A) 30	B) 50	C) 5	D) 40	E) 20
Let the total number of shots be x. Then,   Shots fired by A = 5/8x   Shots fired by B = 3/8x   Killing shots by A = 1/3 of 5/8x = 5/24x   Shots missed by B = 1/2 of 3/8x = 3/16x   Therefore, 3x/16 = 27 or x = (27 x 16/3)= 144.   Birds killed by A = 5x/24 = (5/24 x 144)= 30.   30nswer is 30.
