Q.1: Calculate the amount and compound interest on ₹62,500 for 1 12 years at 8% per annum compounded half-yearly
Ans: Given,
Principal amount (P) =₹ 62500
Rate of interest(R) = 8%
Time(T) = 112 years
There will be 3 half years in given 112 years.
i.e. 32years = 12×3 years = 3 half years
We know that, A=P1+R100n ⇒ A = ₹ 625001+41003 ⇒A = ₹ 62500×2625×2625×2625 ⇒ A = ₹ 70,304
Now, we know
Amount = Principle+ Compound interest
then, Compound interest = Amount in 3 half years-Principle amount
= ₹ 70304-62500
= ₹ 7,804.
Hence, the amount in 32 years is ₹ 70,304 and its compound interest is ₹ 7,804.

Q.2: Calculate the amount and compound interest on ₹8,000 for 1 year at 9% per annum compounded half-yearly. (You could use the year by year calculation using SI formula to verify).
Ans: Given,
Principal amount (P) = ₹ 8000
Rate of interest = 9%
Time =1 year
There are 2 half years in 1 year and rate would be 92% for each half year. We know that,
A=P1+R100n
⇒ A= 80001+92002 ⇒ A=80002092002 ⇒ A= ₹ 8736.20
Compound Interest =A-P
= ₹ (8736.20-8000)
= ₹ 736.20. Therefore, amount for 1 years is ₹ 8736.20 and compound interest
is ₹ 736.20

Q.5: Calculate the amount and compound interest on ₹10,800 for 3 years at 1212% per annum compounded annually.
Ans: Given,
Principal amount (P) = 10800
Time = 3 years
Rate = 252%
Thus, Amount is given by the formula: P1+R100n ⇒ A = ₹108001+252003
= ₹108002252003
=₹10800×225200×225200×225200
= ₹15377.34375
= ₹15377.34
Compound Interest =Amount in 3 years-Principal amount
=₹(15377.34-10800)
=₹4,577.34
Therefore, Compound Interest is ₹4,577.34
