An approach road for a bridge needs 60000 m 3 of soil compacted to a void ratio of 0.7. There are two borrow pits A and B from where the required soil can be taken and transported to the site. The borrow pit A has void ratio 0.85 and borrow pit B has void ratio 0.95. If the cost of excavation of soil and transportation is Rs. 20/10 m 3 for area A and Rs. 22/10 m 3 for area B, which of the borrow area is more economical? G=2.67
