Activity : Note the frequency of two - wheelers , three - wheelers and four - wheelers going past during a time interval , in front of your school gate. Find the probability that any one vehicle out of the total vehicles you have observed is a two - wheeler.

There are twice the number of two wheelers as there are three wheelers and the number of four wheelers are equal to the number of two wheelers. The average of wheel per vehicle is :

There are twice the number of two wheelers as there are three wheelers and the number of 4 wheelers are equal to the number of two wheelers. The average number of wheel per vehicle is :

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 ?

In a municipal parking there are some two wheelers and rest are 4 wheelers. If wheels are counted, there are total 520 wheels but the incharge of the parking told me that there are only 175 vehicles. If no vehicle has a stepney, then the no. of two wheelers is :

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.
