# How are number plates mapped to integer space

I am having a hard time trying to understand as to how the two number plates shown below are converted to their respective integer values.

``````KA01BA0001 is the number of the 2,59,975th vehicle registered.

KA02AA0001 is the number of the 67,59,325th vehicle registered.
``````

as according to my understanding
KA01BA0001 should be 250000

Can you explain your understanding @Apoorv_Goyal as to why KA01BA0001 should be 250000 ? What formula are you using?

KA01AB0001 is 10000th plate
KA01AC0001 is 20000th plate
.

.
KA01AZ0001 is 250000th plate
KA01BA0001 is 260000th plate
@Sumanth_Uppala

So according to my understanding the given plate KA01BA0001 is 260000th plate

@Apoorv_Goyal That is not the correct way of calculating the vehicle count. If you have pulled the breakdown stub then, correct way is given there as a huge hint.

`KA01AA0001` = `1`
`KA01AA9999` = `9999`
`KA01AB0001` = `10000`

From above you can see that for `KA01AB0000` there is no count hence you have to take this into account and debug your logic.
