Question

Two liquids A and B are in the ratio 5 : 1 in container 1 and 1 : 3 in container 2. In what ratio should the contents of the two containers be mixed so as to obtain a mixture of A and B in the ratio 1 : 1?

Options

• 2 : 3

• 4 : 3

• 3 : 2

• 3 : 4

Answer 1

3 : 4

Explanation:

Consider the proportion of liquid A only.

In container 1, it is `5/6`, in container 2 it is `1/4` and the required proportion is `1/2`

Ratio of container 2 to 1 = 4 : 3

Required ratio is 3 : 4.
