I normally get confused with taking the total sales in consideration.
I take the percetage share of battery of 55ah in 1998 & 1992 then do calculation which turns out to be wrong.
So help me out with the explaination.
What I do is 145/605*100 = 23% and 108/543*100 = 19%.
So percetage growth is 4% which is wrong.

We have divided it by 108, because I believe in question it is asked to (compared to 1992) & in 1992, 108 sales is being done.

We are dividing by 108 since in the question they have asked "the sales of 55AH batteries in 1998 compared to that in 1992?".
Here its been compared to 1992 55AH batteries.
So divide by 108.

Why you did subtraction directly we can do 145/108*100 na?

Applying % increase formula because we have to compare batteries from 1992 to 1998.
So actual increase i.e 37/original quantity*100.
i.e.
145108/108*100 = 34%.
So actual increase i.e 37/original quantity*100.
i.e.

It is to be divide by 108 because it is the base year.

By using this formula you can understand @leo. %=((Final valueinitial value)/(initial value))x100.
