When we do following steps:
3000*100/12500*4=96.
We get 96 as a answer, then how 6% is your answer?
Just explain me in detail.
3000*100/12500*4=96.
We get 96 as a answer, then how 6% is your answer?
Just explain me in detail.

Simple To get per year S.I.
15500 -12500 = 750,
Then keep anyone sum as 100%.
100% = 12500,
Then,
X = 750 *100/12500.
X = 6.
15500 -12500 = 750,
Then keep anyone sum as 100%.
100% = 12500,
Then,
X = 750 *100/12500.
X = 6.

Principal amount = 12,500.
Period = 4 Years.
Rate = Find.
So,
S.I = (15,500-12500) = 3000.
Rate ={100 x 3000/12,500/4} = 6%.
Period = 4 Years.
Rate = Find.
So,
S.I = (15,500-12500) = 3000.
Rate ={100 x 3000/12,500/4} = 6%.

You can solve by percentage method;
Simple interest is 3000 for 4years,
So 3000/12500x100% = 24%,
24/4 = 6,
Ans is 6.

To get simple interest from total money after four years (complete period) we need to subtract 12500 from total money.

Here, it is taken 12500 and returns 15500, that means the total amount of interest given is 15500 - 12500 = 3000.

Here SI=PTR/100
So, SI=15500-12500=3000. P=12500, T=4YER,
SO 3000=12500*4*R/100,
i.e R=3000/500= 6% answer.
So, SI=15500-12500=3000. P=12500, T=4YER,
SO 3000=12500*4*R/100,
i.e R=3000/500= 6% answer.

Amount = principal + simple interest.
Dats why we subtracted amount and principal to have the simple interest.

6% interest amount for 12500 is 12500/100 *6 =750.
It is for 4 years thats why 12500+750+750+750+750 = 15500.
It is for 4 years thats why 12500+750+750+750+750 = 15500.

It is like:
15500-12500 = 3000,
1% of Principal = 125,
3000/125=24% for 4 years.
For 1 year = 24/4 = 6%.
15500-12500 = 3000,
1% of Principal = 125,
3000/125=24% for 4 years.
For 1 year = 24/4 = 6%.
