Answer 2

Answer:

rate=10%

Step-by-step explanation:

P=1200

Time=1 year   ⇒ half years=2=n

Rate=r%

compounded half yearly=$P(1+\frac{r}{200} )^{n}$

₹1323=1200$(\frac{200+r}{200} )^{2}$

₹1323=1200$\frac{ (200+r)^{2}}{40000}$

₹1323=$3*\frac{(200+r)^{2} }{100}$

441*100= (200+r)²

(200+r)=21*10=210

r=10
