Income (Rs)	Number of workers
450	2
500	3
550	5
600	8
650	6
700	5
750	1

Answer 1

Income (Rs)	Number of workers
up to 450	2
up to 500	5
up to 550	10
up to 600	18
up to 650	24
up to 700	29
up to 750	30

 Total number of workers = 30 

Half = 15

So median is the wage of 15th worker. The daily wage between the place 10 and 18 = 600 rupees

Median of daily wage = 600 rupees
