12% for 3yr = 36% = 5400.

P = 100%.

=>5400 * 100/36 = 15000.

P = 100%.

=>5400 * 100/36 = 15000.

Interest= principal * rate * time.

5400 = principal * 12/100 * 3.

5400 = principal * 36/100.

5400 * 100 = principal * 36,

540000= 36 principal.

540000/36 = principal.

15000 = principal.

5400 = principal * 12/100 * 3.

5400 = principal * 36/100.

5400 * 100 = principal * 36,

540000= 36 principal.

540000/36 = principal.

15000 = principal.

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.

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

Principal = (100*5400)/(12*3)=540000/36=15000.

Here, 100 * 5400/36 = 15000.

Here, 100 * 5400/12 * 3 = 100 * 150 = 15,000.

5400 is a multiply by 100 then,

12 * 3 means rate of interest of 3 years so,

540000/ 36 = 15000.

So,

Principle amount = 15000.

12 * 3 means rate of interest of 3 years so,

540000/ 36 = 15000.

So,

Principle amount = 15000.
