    Explanation

    Total income = Profit earned + Total investment in the year. Profit earned = (Investment × Profit percentage) ÷ 100 Profit percentage of A in 2009 = 75% Profit percentage of B in 2009 = 80% Say IA and IB are investments by A and B respectively in 2009. Given IA + IB = 27 lakhs Also IB = 0.50 × IA ⇒ 1.5 × IA = 27 lakhs ⇒ IA = 18 lakhs and IB = 9 lakhs ∴ Profit earned by A in 2009 = (18 × 75)/100 = 13.5 lakhs Profit earned by B in 2009 = (9 × 80)/100 = 7.2 lakhs ∴ Total profit earned by two companies in 2009 = 13.5 + 7.2 = 20.7 lakhs
