Given length of wire = 2000 mts
cost of cable below water = 900 * 5 = 4500
cost of cable on the bank of river= (2000-900) * 4 = 4400
Total cost = 4500 + 4400 = 8900.

Power unit by the bank of a river=900 meters.
Now,cost of the cable on the bank is Rs. 4/- meter.
Then, total cost of the cable on the bank= Rs. 900*4= Rs.3600
The length under water= (2000-900) meters = 1100 meters
Then,the total cost under water= Rs.5 * 1100= Rs.5500
Then total cost= RS.(3600+5500)= Rs. 9100
