The average daily wage of 10 workers is Tk.400. If the lowest wage is Tk.300, then what is the possible maximum wage?
A
800
B
1000
C
1200
D
1300
Correct Answer: 1300
Let the sum of wages of 10 workers be S.According to the question, the average daily wage of 10 workers is Tk. 400. Therefore, we can write:S/10 = 400S = 4000Now, let's assume that the maximum wage is M. Since the lowest wage is Tk. 300, we know that M is greater than or equal to 300. Therefore, we can write:M ≥ 300We also know that the sum of wages is S = 4000. Therefore, we can write:M + 9(300) ≤ SM + 2700 ≤ 4000M ≤ 1300Therefore, the maximum wage is Tk. 1300.
