Compute the amount and the compound interest in each of the following by using the formulas when: (a)Principal = Rs 3000, Rate = 5%, time = 2 years . (b)Principal = Rs 3000, rate = 18%, time = 2 years . (c)Principal = Rs 5000, rate = 10 %, time – 2 years (d)Principal = Rs 2000, rate = 4%, time = 3 years (e)Principal = Rs 10000, rate 20% per annum compounded half-yearly, time = 2 years (f)Principal = Rs 160000, rate = 10 paise per rupee per annum compounded half-yearly, time = 2 years.
