Compute the amount and the compound interest in each of the following by usingthe formulae when :
(i)Principal = Rs 3000, Rate = 5%, Time = 2 years
(ii)Principal = Rs 3000, Rate = 18%, Time = 2 years
(iii)Principal = Rs 5000, Rate = 10 paise per rupee per annum, Time = 2 years
(iv)Principal = Rs 2000, Rate = 4 paise per rupee per annum, Time = 3 years
(v)Principal = Rs 12800, Rate = 7 ½ %, Time = 3 years
(vi)Principal = Rs 10000, Rate = 20% per annum compounded half-yearly, Time =2 years
(vii)Principal = Rs 160000, Rate = 10 paise per rupee per annum compounded halfyearly, Time = 2 years
