Question

The average daily income of a daily wage worker, in the month of November is Rs. 200. If his average income on 1st 13 days of the month is Rs. 60 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. 530 Correct Answer Incorrect Answer
C Rs. 280 Correct Answer Incorrect Answer
D Rs. 590 Correct Answer Incorrect Answer
E Rs. 1140 Correct Answer Incorrect Answer

Solution

His total income in the month = 30 × 200 = Rs. 6000
His income of 1st 13 days = 13 × 60 = Rs. 780
His income in last 15 days = 15 × 120 = Rs. 1800
Therefore, his income in the remaining two days = 6000 – (780 + 1800) = Rs. 3420
Required average = (3420/3) = Rs. 1140
