A power unit is there by the bank of the river of 700 meters width. A cable is made from power unit to power a plant opposite to that of the river and 1400mts away from the power unit. The cost of the cable below water is Rs. 18/- per meter and cost of cable on the bank is Rs.15/- per meter. Find the total of laying the cable.

• Rs 23100. river width is 700 so cost is 700*18=12600. since distance between power unit and plant is 1400 m . so length of cable outside water is 700m. so cost is 700*15=10500. total cost is 12600+10500=23100
