) The ratio of elements in two alloys are 5:3 and 1:2.
Let the weight of 1unit of each alloy be 8 x 3 = 24.
Then alloy A will have elements weighing 15 and 9.
Alloy B will have elements weighing 8 and 16.
Now these two alloys are mixed in the ratio 4:3.
So, weight of elements taken from alloy A = 60 and 36.
Weight of elements taken from alloy B = 24 and 48.
Ration of elements in final alloy = (60+24)/(36+48) = 1:1.
Hence, a is the answer.
