Calculating Average Hourly Wage

To find the average wage per hour paid by the contractor, we need to calculate the weighted average based on the number of skilled and unskilled workers and their respective hourly rates.

Key Information Extraction

Number of skilled workers: 25
Hourly wage for skilled workers: ₹30
Number of unskilled workers: 5
Hourly wage for unskilled workers: ₹24
Total number of workers: 25 + 5 = 30

Weighted Average Calculation Steps

Calculate Total Earnings for Skilled Workers:
Total skilled earnings = (Number of skilled workers) \times (Hourly wage for skilled workers)

Total skilled earnings = 25 \times ₹30 = ₹750
Calculate Total Earnings for Unskilled Workers:
Total unskilled earnings = (Number of unskilled workers) \times (Hourly wage for unskilled workers)

Total unskilled earnings = 5 \times ₹24 = ₹120
Calculate Total Hourly Earnings for All Workers:
Total earnings = Total skilled earnings + Total unskilled earnings

Total earnings = ₹750 + ₹120 = ₹870
Calculate the Average Wage Per Hour:
Average wage = \frac{\text{Total hourly earnings}}{\text{Total number of workers}}

Average wage = \frac{₹870}{30}

Average wage = ₹29
