The respective percentage alcohol concentrations of the cocktails are provided in the chart below.

Except for Russian Heat, no other cocktail has more than 30% Vodka. So Russian Heat has to be one of the choices of cocktail. 

Now the cost must also be minimum possible. 

So the only other choice will be Teqnical, as it costs the least at Rs 160 per peg and also has the second highest content of Vodka. 

Applying alligation,

We find that to have at least 30% content of Vodka, the ratio of Russian Heat and Teqnical must be 12 : 12, that is 1 : 1 

So cost = (1*240 + 1*160) / 2 = Rs 200. 

Hence the least cost of a peg of a drink which contains at least 30% of Vodka is Rs 200
