Given:

Amount = ₹12167

Time = 3 years.

Rate = 15%

To find :

What is the sum ?

We need to find Principal because principal is known as sum.

For Finding Principal ,

According to the question,

$a = ( 1\frac{p}{100} ) {}^{n}$

$12167 = p(1 + \frac{15}{100} ) {}^{3}$

$12167 = p( \frac{23}{20} ) {}^{3}$

$12167 \times \frac{8000}{12167}$

By solving this we will get the sum,

we will cut the both 12167

Remaining will be ₹8000.

Hence, the sum is = ₹ 8000
