Question

Ravi invested an amount of ₹20,000 at 20% per annum. Find the compound interest received on the investment if the interest is compounded half-yearly.​

Answer 1

Step-by-step explanation:

20000 10℅

Ci=Si-P

SI=20000×10×T/100

Si/T=2000

Answer 2

Answer:

Step-by-step explanation:

Principle = p = 20,000

Rate of interest = i = 20%

Time = 1 yrs

Compounded half yearly

$\bold{\green{\boxed{CI = p(1+i)^n-1}}}$

$\bold{CI = 20,000(1+0.1)^2-1}$

$\bold{CI = 20,000(1.1)^2-1}$

$\bold{CI = 20,000(0.21)}$

$\boxed{\bold{CI = 4,200}}$

Thus the interest on investment is 4,200 and the final amount after one year is 24,200
