According to mass emission standards in India, 2, 3 and 4 wheelers types of vehicles (through out the country) falls under the norm:

On a particular day , at a crossing in a city , the various types of 240 vehicles going past during a time interval were observed as under : Out of these vehicles , one is chosen at random . What is the probability that the chosen vehicle is a two-wheeler ?

On a particular day, at a crossing in a city, the various types of 280 vehicles going past during a time interval were observed as under: |{:("Type of vehicle","Two wheelers","Three wheelers","Four wheelers"),("Frequency"," 91"," 63"," 126"):}| Out of these vechicles , one is chosen at random, what is the probability that the chosen vechicle is (i) a four wheeler (ii) a two wheeler (iii) a three wheeler?

Direction: A vehicle manufacturing company sells three types of vehicles, 4 wheelers, 3 wheelers and 2 wheelers in two different sessions 2010-2012 and 2013-2015. In the first session, the ratio of 4 wheelers, 3 wheelers and 2 wheelers sold is 1 : 2 : 2. Also, 3 wheelers sold in this session is 20% more than the same type of wheelers sold in the second session. The total vehicles sold in session 2010-2012 is 12 lacs. The 4 wheelers sold in 2013-2015 is 20,000 more than the 2 wheelers sold in 2010-2012. The 2 wheelers sold in 2013- 15 are 12.5% more than that of sold in 2010-12. If in session 2010-2012, the production of 4 wheelers and 2 wheelers are 2.8 lacs and 5 lacs, respectively, then find the ratio of unsold vehicles of the same type.

The number of 2 wheelers are twice the number of 3 wheelers and the number of 4 wheelers are equal to the number of 2 wheelers. Find the average of wheel per vehicle.
