    Solution

    ATQ,

    Let the initial investments of ‘Arjun’ and ‘Bheem’ be Rs. ‘5x’ and Rs. ‘6x’, respectively

    Then, increased investment of ‘Arjun’ = 5x × 1.4 = Rs. ‘7x’

    Increased investment of ‘Bheem’ = 6x × 1.5 = Rs. ‘9x’

    So, ratio of profit shares of ‘Arjun’ and ‘Bheem’ = (5x + 7x):(6x + 9x) = 12x:15x = 4:5

    So, profit share of ‘Arjun’ at the end of two years = Rs. 9000 × (4/9) = Rs. 4,000
