SolutionIncome from 7/2% stock at 75 = Rs. 7/2*75 * 900 = Rs.42 Income from 3% stock at 68 = Rs. 3/68 * 850 = Rs. 37.50 Total income from these two stocks = Rs 79.50 But total income from the three stocks Rs. 5/100 * 2490 = Rs.124.50 Therefore Income from the third stock Rs. (124.50 - 79.50) = Rs.45 Investment in this case = Rs.2490 - (900+850) = Rs.740 If income is Rs.45, investment = Rs.740 If income is Rs.6, investment = Rs. 740/45 * 6 = 296/3 So he buys 6% stock at 296/3
