New Collection of Sampreet

I brought a set of four cars for Sampreet from Nagpur. Green Colour, plastic cars - three cars & one jeep. Two small sharpeners and a helicopter. He doesn't know about the helicopter that will be in the buffer for the time being. My friend Ravindra Verma (Ravi) gifted him a puzzle. Sampreet by the end of the day has solved all of them.
