A invested a certain amount in Debt and Equity mutual funds in the ratio of 3: 7 respectively. At the end of one year, he earned a total dividend of 30% on his investment. After one year he reinvested the amount including dividend in the ratio of 5: 8 in Debt and Equity mutualFunds. If the amount reinvested in Equity mutualFunds was Rs. 98,400, what was the original amount invested in Equity mutualFunds?
Total amount reinvested by A = 98400 x (13/8) = 159900 Total amount invested by him at starting = (100/130) x 159900 = 123000 Required amount = (7/10) x 123000 = 86100
