    Question

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

    month of March is Rs. 200. If his average income on 1st 13 days of the month is Rs. 80 and on last 15 days of the month is Rs. 120, then find his average income on remaining three days of the month.
    A Rs. 810 Correct Answer Incorrect Answer
    B Rs. 800 Correct Answer Incorrect Answer
    C Rs. 1120 Correct Answer Incorrect Answer
    D Rs. 360 Correct Answer Incorrect Answer
    E Rs. 700 Correct Answer Incorrect Answer

    Solution

    His total income in the month = 31 × 200 = Rs. 6200
    His income of 1st 13 days = 13 × 80 = Rs. 1040
    His income in last 15 days = 15 × 120 = Rs. 1800
    Therefore, his income in the remaining two days = 6200 – (1040 + 1800) = Rs. 3360
    Required average = (3360/3) = Rs. 1120
