Average daily wage of 50 workers of a factory was Rs 200. Each worker is given a raise of Rs 20.
What is the new average daily wage?


#2

Increase in wages of each worker = Rs 20
Total increase in wages = 50 x 20 = Rs 1000
Total wages before increase in wages = 50 x 200 = 10000
Total wages after increase in wages = 10000+1000 = Rs 11000
New average wage =Σx / n = 11000/50 = 220
Thus, mean wage will increase by Rs 20.
