Why you did subtraction directly we can do 145/108*100 na?
Swathi said:   1 decade ago
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 should we divide by 108 please can anyone explain me?

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.

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.
