    D 3200 Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    We can say that initial investment made by Adam is Rs.'a' Initial investment made by Zampa is Rs. (7000 – a) Ratio of profit share of Adam to Zampa = (a × 7 + 1.2a × 5):[(7000 – a) × 7 + 0.6 × (7000 – a) × 5]  = 13a:(70000 – 10a) According to question; [13a/(70000 – 10a)] = (1612/3100) = 13/25 325a = 910000 – 130a 455a = 910000 a = 2000 Initial investment made by Adam = Rs.2000
