Question

Find the compound interest on rs 160000 for one year at 20%per annum if the interest is compounded quarterly.​

Answer 1

Answer:

194481

Step-by-step explanation:

yearly 20% means quarterly 5%,

160000×(105/100)⁴= 160000× 21/20×21/20×21/20×21/20=21⁴=194481

Answer 2

$\bigstar\huge\bf\underline{\underline{\red{Answer:-}}}$

$\bigstar\bf\underline\green{Given:-}$

• $\bf Principal \ (p) \ = \ RS.160000$

• $\bf Rate \ (r) \ = \ 20 \ percent$

$\bigstar\bf\underline{\Blue{To \ find:-}}$

• $\bf The \ compound \ Interest$

$\bigstar\bf\underline\orange{Solution:-}$

$\bf Principal \ (p) \ = \ RS.160000$

$\bf Rate \ (r) \ = \ 20 \ percent$

$\bf\implies 5 \ percent$  $\bf (per \ quaterly)$

$\bf Time \ (t) \ = \ 1 \ year \ = \ 4 \ quater \ months$

$\bf Compound \ interest \ = \ p[(1+\frac{r}{100})^{t}-1]$

$\bf\implies 160000[(1+\frac{5}{100})^{4}-1]$

$\bf\implies 16000[(1.05)^{4}-1]$

$\bf\implies\underline 34,481$

$\boxed{\boxed{\purple{\bf The \ Compound \ Interest \ = \ RS.34.481}}}$
