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

Let me explain guys
12500 is the actual amount after 4 years amount will be 15,500 with simple interest alright so that we need to find what per cent of interest they paid for 12,500.
15,500-12500
3000.
SI = PTR/100.
Si = 100*r/p*t.
100*3000/12500*4,
6%.

4.65*10 = 46.5.
46.5*2 = 93.
Hence 20 days.
46.5*2 = 93.
Hence 20 days.

Here.
P = 12500.
T = 4 years.
Amount = S.I+P.
S.I = Amount-P.
S.I = 15500-12500 = 3000.
R = 100*S.I/P*T = 100*3000/12500*4 = 6%.
P = 12500.
T = 4 years.
Amount = S.I+P.
S.I = Amount-P.
S.I = 15500-12500 = 3000.
R = 100*S.I/P*T = 100*3000/12500*4 = 6%.

12500*6% = 750.
750*4 = 3000.
12500+3000 = 15500.
750*4 = 3000.
12500+3000 = 15500.

What means PTR and SI?

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

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%.
