NEW DELHI: Petrol price inched towards the Rs 100-mark at Mumbai on Tuesday after gas prices were increased again. Petrol cost was raised by 23 paise a litre and diesel by 25 paise a litre, according to a cost notification of state-owned gas retailers. The increase – 13th this month – driven petrol and gas prices to record-high rates throughout the nation. Petrol cost in Delhi climbed to Rs 93.44 a litre and petrol to Rs 84.32 per litre. In Mumbai, gas cost grew to Rs 99.71 a litre and petrol to Rs 91.57 a litre. Rates had crossed the Rs 100-mark in a number of towns in Rajasthan, Madhya Pradesh and Maharashtra and the most recent increase, the cost in Mumbai also was inching towards this amount. Fuel prices vary from state to state based upon the prevalence of local taxation like VAT and freight costs. Rajasthan levies the greatest value-added taxation (VAT) on gasoline in the nation, followed by Madhya Pradesh and Maharashtra. Oil businesses revise rates of gas and gas each day based on average cost of grade gas at the worldwide marketplace in the previous 15-days, and international exchange prices. That is the 13th rise in costs since May 4, even once the petroleum oil companies finished an 18-day hiatus in speed revision they discovered through assembly elections in countries including West Bengal. Sri Ganganagar district of Rajasthan had the priciest gas and gas in the nation at Rs 104.42 a litre and Rs 97.18 per litre, respectively.
