Q3 of 55 Page 116

Name the city in our country where the entire public road transport runs on CNG.

In Delhi, the entire public transport runs on CNG. By the end of year 2002, all the buses in Delhi were converted to run on CNG. This was done because CNG is better than diesel and petrol as it burns most efficiently and in the automobiles, very little of CNG is left unburnt. Also, CNG is cheaper than petrol and diesel, can’t be siphoned off (drawn out) by the thieves and can’t be adulterated.
