A building contractor employs 20 male, 15 female and 5 teen workers. Male worker gets Rs. 25 per day, a female worker gets Rs. 20 per day and a teen worker gets Rs. 8 per day. The average wage per day paid by the contractor is ______?
- Rs. 23
- Rs. 20
- Rs. 21
- None of these
Explanation
To find the average wage per day:
Total daily wages:
Male workers: 20 × Rs. 25 = Rs. 500
Female workers: 15 × Rs. 20 = Rs. 300
Teen workers: 5 × Rs. 8 = Rs. 40
Total daily wages = Rs. 500 + Rs. 300 + Rs. 40 = Rs. 840
Total number of workers = 20 + 15 + 5 = 40
Average wage per day = Total daily wages / Total number of workers
= Rs. 840 / 40
= Rs. 21
