Question 2. \nPrincipal = \u20b9 1000, Rate = 8% per annum. Fill in the following table and find which type of interest (simple or compound) change is in direct proportion with time period. \n \nAnswer: \nCase of Simple Interest \n[P = \u20b9 1000, r = 8% p.a.] \n \nIn each case the ratio is the same. \nThe simple interest changes in direct proportion with time period. \nCase of Compound Interest [P = \u20b9 1000, r = 8% p.a.] \n \n\\(\\frac{\\mathrm{CI}}{\\mathrm{T}}\\) is not the same in each case. \n\u2234 The compound interest does not change in direct proportion with time period.<\/p>\n
