(C) Given: Principal $(P) = Rs. 10000$,Annual Rate $= 20 \%$,Time $= 1$ year $6$ months $= 1.5$ years.Since the interest is calculated half-yearly:Rate $(R) = \frac{20}{2} = 10 \%$ per half-year.Time $(n) = 1.5 	imes 2 = 3$ half-years.Compound Interest $(C.I.) = P \left[ \left( 1 + \frac{R}{100} ight)^n - 1 ight]$.$C.I. = 10000 \left[ \left( 1 + \frac{10}{100} ight)^3 - 1 ight]$.$C.I. = 10000 \left[ \left( \frac{11}{10} ight)^3 - 1 ight]$.$C.I. = 10000 \left[ \frac{1331}{1000} - 1 ight]$.$C.I. = 10000 \left[ \frac{331}{1000} ight] = Rs. 3310$.
