p=?
r=12%
t=3 yrs
p*t*r/100=s.i
p*3*12/100=5400
p*36=5400*100=540000
p=540000/36
p=15000
r=12%
t=3 yrs
p*t*r/100=s.i
p*3*12/100=5400
p*36=5400*100=540000
p=540000/36
p=15000

36% ----> 5400 then 1% ----> 5400/36 =150.
100%---->x
So, x = 150 * 100.
=15000.
100%---->x
So, x = 150 * 100.
=15000.

5400/3 = 1800 (one year intrest).
Hence principal amount = 1800/.12 = 15000.
Hence principal amount = 1800/.12 = 15000.

One year int is 36 for 100 so total int is 5400 so 5400*100/36 = 15000.

S.I = PRT,
5400 = P * 12 * 3/100,
540,000 = 36P,
540,000/36,
= 15,000.
5400 = P * 12 * 3/100,
540,000 = 36P,
540,000/36,
= 15,000.

12% for 3yr = 36% = 5400.
P = 100%.
=>5400 * 100/36 = 15000.
P = 100%.
=>5400 * 100/36 = 15000.

Every year = 5400/3 = 1800, now 12%=1800, then 100%= 15000.
