total no, of workers= 75 

mean salary= Rs. 5680

total money= 75*5680 = Rs. 426000 

no of worker with salary rs.  5400= 25

total money paid to 25 workers = 25*5400 = 135000

no. of workers with rs. 5700 slaray= 30

total money paid to 30 workers.= 30*5700 = 171000

.total worker. paid= 25+30= 55

remaining  workers= 75- 55 = 20

total money paid to 55 workers= Rs. 171000+ rs. 135000

= rs. 306000

remaining money= Rs 426000 - rs 306000 = rs. 120000

average of remaining  money = remaining money/remaining workers..

= rs.. 120000/20

= Rs 6000
