In what proportion water must be added to spirit to gain 20% by selling it at the cost price ?

1:5

2:5

5:1

3:2

Let the C.P of spirit be = Rs.10 per litre

Then S.P l litre of the mixture = Rs. 11

Profit = 20%

Therefore, C.P of the mixture = Rs. [100/120×10] = Rs. 25/3 per litre

0 10

25/3

5/3 25/3

Therefore, Ratio of water and spirit = 1 : 5

Hence, option 1 is the correct answer.
