Sorry the question has some mistake, I think question is

Find the Principal amount, the compound interest be Rs.625 for 2 years at 9% per annum payable semi annually.

Answer:

Amount I.e. Principal amount is 526 rupees.

Step-by-step explanation:

The formula is

Compound interest = p$(1+r/100)^{n}$

here p= principal amount, that we have to calculate

• r=9% interest rate
• n= number of years is 2

⇒625=$P[1+9/100]^{2}$

⇒625=p[1+9/100][1+9/100]

⇒625=p[(100+9)/100][(100+9)/100]

⇒625=p[(109/100)][(109/100)]

⇒p=(625×100×100)/(109×109)

⇒p= 526 rupees.

Required Amount is 526 Rs.
