Find the value of r if Rs 100 double itself in 10 years (log 2 = 0.6931). 24:25 Que. 21 In a bank, principal increases continuously at the rate of 5% per year. An amount of Rs 1000 is deposited with this bank, how much will it be worth after 10 years (eo.5 = 1.648). 42:39 Que. 22 In a culture, the bacteria count is 1,00,000. The number is increased by 10% in 2 hours. In how many hours will the count reach 2,00,000, if the rate of growth of bacteria is proportional to the number present? 01:06:49 Que. 23 The general solution of the differential equation 01:19:57 Website Overview ======================================================= Why study from Magnet Brains?
