(ii) Principal = Rs. 3000, Rate = 18%, Time = 2 years

(iii) Principal = Rs. 5000, Rate = 10 paise per annum, Time = 2 years

(iv) Principal = Rs. 2000, Rate = 4 paise per annum, Time = 3 years

(v) Principal = Rs. 12800, Rate = 7%, 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 half yearly, Time = 2 years.
