Actual Price of petrol,Govt. eating our pocket by taking the Name of Rise in Crude prices,

Actua price of Petrol is very low if sold without taxes .Here is the breakdown of the taxes charged by the government in various forms. From the time it is refined to the time it reaches the consumers.

1. Excise duty  : 14.35 rupees per liter 
2. Customs duty : 7.5 percent
3. Sales tax or VAT  : 20 percent.

The total taxes amount to 45 percent of the final cost of the petrol.
If a barrel of crude oil in International market is $140 and if the petrol prices were left to the market fluctuations then the cost of petrol in retail market would be 70 rupees per liter. Now crude oil in International market $110 which is way below $140 mark now petrol rate in Delhi is 66 Rs. but actul rate should be 45% less then actual be. Then why not govt. is reducing taxes instead of hiking prices.
