    Solution

    ATQ,

    Let the efficiency of Mohit be 5x units/day

    So, efficiency of Rohit = 5x × (60/100) = 3x units/day

    Work done in first 10 days = 10 × (3x + 5x) = 80x units

    Work done by Mohit in 8 days = 8 × 5x = 40x units

    Total work = 80x + 40x = 120x units

    Work done by Mohit = 10 × 5x + 8 × 5x = 90x units

    So, Mohit's share = (3600 / 120x) × 90x = Rs. 2700
