Union Finance Minister Pranab Mukherjee said in Mumbai today that petrol price rise was inevitable because of a steep increase in price of crude oil in the international market. Drawing comparisons between the prices in 2000 and 2011, the Finance minister said that the price of crude oil has gone up by 5 to 6 times in a decade. He said nearly 75 per cent of the country's 100 million tonnes of crude requirement is met by imports.Mukherjee was speaking to reporters in Mumbai after addressing a review meeting of the West Zone states on wide ranging issues pertaining to credit and flow of funds to the farm sector. A memorandum of understanding was also signed between the India Infrastructure Finance Company Ltd, LIC and Infrastructure Development Finance Company to fund various infrastructure projects.
