Why aren't we using the formula of P (1+R/100) ^N? Please explain to me.

262500 = x% of 175000
i.e. 150% of 175000
Thus, a 50% increase from 100%.
50% increase in 10 years, so 5% increase per year.
i.e. 150% of 175000
Thus, a 50% increase from 100%.
50% increase in 10 years, so 5% increase per year.

The population increased in 10 years 262500 - 175000 = 87500. For a decade that is for 10 years
Per year increase 87500/10= 8750.
Avg per cent increase in population per year= 8750/175000*100 = 5 per cent.
Per year increase 87500/10= 8750.
Avg per cent increase in population per year= 8750/175000*100 = 5 per cent.

We are taking 10 years since it has been mentioned in the question that there is an increase in a decade.
So, 1 decade = 10 years.
So, 1 decade = 10 years.

It was mentioned increase was there in a decade means
we have a 50% increase in 10 years.
Now we were asked in 1 year =?
Simply unitary method
10 -> 50
1 -> ?
1*50/10 = 5%.

Why not directly the formula of compound interest for finding population after nth years is not used?
Anyone, please clarify it.

100-(20+60+10) = 10%.
10% = 30 means 100% = 300.
10% = 30 means 100% = 300.
