1. Rs 350
2. Rs 65
3. Rs 650
4. Rs 450

Answer 1

Correct Answer - Option 3 : Rs 650

Given

9 days wages = Rs.3600

Average wages of first 5 days = Rs.200

Formula used

Average = (Sum of all observations) / (Number of observations)

Calculation

9 days wages = Rs.3600

Five days wages = 5 × 200 = 1000

So, Remaining 4 days wages = 3600 - 1000 = 2600

Average wages for remaining 4 days = 2600/4 = Rs.650

∴ Average wages of remaining days is Rs.650.
