Wages in Rupees
The maximum wage (in Rupees), such that at least 50% of the labourers definitely earn more than that, is
Let's tabulate the information in the graph ,we get
The total number of labourer = 100
50% of the total labourers is 50 who will fall in the range >=280 - <320
$$\therefore$$ The maximum wage such that at least 50% of the labourers definitely earn more than that is 280
Hence B is the correct answer.
