Given that principal is Rs 12,000 , Amount is Rs 15972 and the rate of interst is 10% .

We know that the ,

★ Simple Interest = P × R × T / 100 ★

Now Amount is equal to ,

❒ Amount = SI + Principal .

➳ Amount = SI + Principal.

➳ Rs 15,972 = SI + Rs 12,000.

➳ SI = Rs ( 15,972 - 12,000).

➳ SI = Rs 3972 .

Now , put the values in formula to find Simple Interest :-

➳ SI = P × R × T / 100.

➳ Rs 3972 = Rs 12,000 × 10% × T / 100

➳ T = Rs 3972 × 100/1200 × 10

➳ T = 331/100.

➳ T = 3.31 yrs .

Hence the Time period is 3.31 yrs .
