Question

calculate the amount of rupees 18000 is invested at 15 annum compounded half yearly for one year

Answer 1

p= 18000 , rate 15 % . amount =p + si . si = prt÷100 18000× 0.5 ×15 ÷100. now u can solve.= 135000÷ 100 = 1350 = si. amount = 1350+18000= ₹19350

Answer 2

Answer:

20801.25 rupees

Step-by-step explanation:

Since, the amount formula in compound interest is,

$A=P(1+\frac{r}{n})^t$

Where,

P = principal amount,

r = annual rate,

n = number of compounding periods in a year,

t = number of years,

Here, P = 18000 rupees, r = 15% = 0.15, t = 1, n = 2,

Hence, the amount would be,

$A=18000(1+\frac{0.15}{2})^2 = 18000(1+0.075)^2 = 18000(1.075)^2 = 20801.25\text{ rupees}$
