    Question

    Average monthly income of 35 workers is ₹52,000. Two

    new workers earning (r + 8000) and (r - 2000) join, and the average rises to ₹53,000. Find (r - 25,000).
    A 42,000 Correct Answer Incorrect Answer
    B 43,000 Correct Answer Incorrect Answer
    C 42,500 Correct Answer Incorrect Answer
    D 41,000 Correct Answer Incorrect Answer

    Solution

    37 × 53,000 − 35 × 52,000 = r + 8000 + r − 2000
    2r + 6000 = 1,961,000 − 1,820,000 = 141,000
    2r = 135,000
    r = 67,500
    r − 25,000 = 42,500
