Answer:
Let the required be x : y
Liquid A in x litres of mixture in container 1
= 5x/6 litres
Liquid B in x litres of mixture in container 1
= x/6 litres
Liquid A in y litres of mixture in container 2
= y/4 litres
Liquid B in y litres of mixture in container 2
= 3y/4 litres
Therefore Liquid A : Liquid B
Given,
=> 5x/6 + y/4 = x/6 + 3y/4
=> 5x - x/6 = 3y/4 - y/4
=> 4x/6 = 2y/4
=> 2x/3 = y/2
=> x/y = 3/4.
Therefore in 3/4 ratio the contents of the two containers be mixed so as to obtain a mixture of A and B in the ratio 1 : 1
