The Thane unit of the NCP on Friday put up billboards across the city "celebrating" the cost of petrol hitting the century mark, and took a swipe at the Narendra Modi government by telling people such price rise was the Centre's idea of "achche din".

Thane NCP president Anand Paranjpe said fuel prices were rising over the past fortnight and petrol was retailing at Rs 100 in the city.
