Please mark me as Brainlist

Step-by-step explanation:

Let C.P. of milk be Re. 1 per litre.

Then; S.P. of 1 litre of mixture = Re. 1.

Gain obtained = 20%.

5 C.P. of 1 litre of mixture = Rs ( 100/120 X 1 ) = Rs. 5/6

By the rule of alligation, we have :

C.P. of 1 litre of water C.P. of 1 litre of milk

0 Mean price

Rs. 5/6 Rs. 1

(1 - 5/6) = 1/6 (5/6 - 0) = 5/6

so Ratio of water and milk = 1/6 : 5/6 = 1 : 5
