## Steps to find average number of cars sold

Step 2:Add the number of parts of 2008,2010 and 2012

Step 3:Multiply the result obtained in step 2 by the scale

Step 4:Divide the result obtained in step 3 by the number of years

Step 5:Multiply the result obtained in step 4 by original units of expression(in this example it is 1 production in thousands)

Finding the number of parts in 2008,2010 and 2012

Number of parts of A type cars in 2008=3

Number of parts of A type cars in 2010=8

Number of parts of A type cars in 2012=6

Adding all the parts of A type cars in 2008,2010 and 2012

We get,

3+8+6=17

Multiplying the result by the scale(5)

we get,17 x 5=85

Dividing the result by number of years(3)

we get,85/3=28.333333

Multiplying the result by 1000

we get,28333

**Ans Average =28,333 approximately**
