Answer 1

Answer:

Step-by-step explanation:

Let the number of days to complete the work be x.  

According to the question,  

x20 + x−224 + x−530 = 1

= 6x+5(x−2)+4(x−5)120=1

= 6x+5x+4x=120+10+20

= 15x = 150

Therefore, x = 10

Therefore, Work done by A = 1020=12

Therefore, Share of A from the assured money = 12×5400 = Rs.2700
