Answer 2

Answer:

7:5

Step-by-step explanation:

Milk in 1 litre mixture of A = 4/7 litre.

Milk in 1 litre mixture of B = 2/5 litre.

Milk in 1 litre mixture of C = 1/2 litre.

By rule of alligation we have required ratio X:Y

X : Y

4/7 2/5

\ /

(Mean ratio)

(1/2)

/ \

(1/2 – 2/5) : (4/7 – 1/2)

1/10 1/1 4

So Required ratio = X : Y = 1/10 : 1/14 = 7:5
