Correct Answer - Option 4 : Rs. 410
Given:
Average wages in a week = Rs.630
Average wages for 5 days = Rs. 800
Formula Used:
Average = Sum of all items / Number of items
Calculation:
Average wages of a week
⇒ Average wages = Sum of wages of a week/Number of days
⇒ 630 = Sum of wages of a week/7
⇒ 4410 = Sum of wages of a week ………………… (1)
Average wages for 5 days
⇒ Average wages = Sum of wages for 5 days/Number of days
⇒ 800 = Sum of wages for 5 days/5
⇒ 4000 = Sum of wages for 5 days …………………… (2)
Wages for 2 days = Wages of a week – Wages for 5 days
⇒ Wages for 2 days = 4410 – 4000
∴ Wages for 2 days = Rs. 410
The correct option is 4 i.e. Rs. 410
