Solution

Let each part be x.
Vol of A= 5x ;
Vol of B= x ; Total Vol= 6x.

Container 2:
Let each part be y.
Vol of A= y ; 
Vol of B= 3y; 
Total Vol= 4y.

After Mixing:
Vol of A= 5x + y
Vol of B= x + 3y
As Ratio of A:B is 1:1, hence
5x+y = x+3y
2x = y
So,
Ratio of Total Vol 1 : Total Vol 2 =
6x / 4y 
= 6x / 4(2x) 
= 6/8 = 3/4.

1:2 is the correct answer. Bcz ratio of content added is asked not the ratio of volume of container.
