    when they first started their businesses. After a year, N increased his investment by 40% while M withdrew 25% of his original stake. After 2 years, M made a profit of Rs.5040. Determine N's profit portion.
    A Rs.5773 Correct Answer Incorrect Answer
    B Rs.7030 Correct Answer Incorrect Answer
    C Rs.6344 Correct Answer Incorrect Answer
    D Rs.5400 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Ratio of the profits earned by M and N = {6400 + (0.75 × 6400)}:{5000 + (1.4 × 5000)} = (6400 + 4800):(5000 + 7000) = 11200:12000 = 14:15 Therefore, profit share of 'N' = 5040 × (15/14) = Rs.5400
