    Question

    The average daily income of a daily wage worker, in the

    month of January is Rs. 100. If his average income on 1st 13 days of the month is Rs. 50 and on last 16 days of the month is Rs. 125, then find his average income on remaining two days of the month.
    A Rs. 810 Correct Answer Incorrect Answer
    B Rs. 800 Correct Answer Incorrect Answer
    C Rs. 225 Correct Answer Incorrect Answer
    D Rs. 610 Correct Answer Incorrect Answer
    E Rs. 700 Correct Answer Incorrect Answer

    Solution

    His total income in the month = 31 × 100 = Rs. 3100
    His income of 1st 13 days = 13 × 50 = Rs. 650
    His income in last 16 days = 16 × 125 = Rs. 2000
    Therefore, his income in the remaining two days = 3100 – (650 + 2000) = Rs. 450
    Required average = (450/2) = Rs. 225
