MCQ - 364-13131

Question:

The average wages of a worker during a fortnight comprising 15 consecutive working days was Rs.90 per day. During the first 7 days, his average wages was Rs.87/day and the average wages during the last 7 days was Rs.92 /day. What was his wage on the 8th day?

Correct Answer: D

Explanation:

The total wages earned during the 15 days that the worker worked :

=15×90=Rs.1350.

The total wages earned during the first 7 days = 7×87 = Rs. 609.

The total wages earned during the last 7 days = 7×92 = Rs. 644.

Total wages earned during the 15 days = wages during first 7 days + wage on 8^th day + wages during the last 7 days.

1350=609+ wage on 8^th day +644

wage on 8th day = 1350−609−644 = Rs. 97
